Add Debian package registry (#24426)

Co-authored-by: @awkwardbunny This PR adds a Debian package registry. You can follow [this tutorial](https://www.baeldung.com/linux/create-debian-package) to build a *.deb package for testing. Source packages are not supported at the moment and I did not find documentation of the architecture "all" and how these packages should be treated. ![grafik](https://user-images.githubusercontent.com/1666336/218126879-eb80a866-775c-4c8e-8529-5797203a64e6.png) Part of #20751. Revised copy of #22854. --------- Co-authored-by: Brian Hong <brian@hongs.me> Co-authored-by: techknowlogick <techknowlogick@gitea.io> Co-authored-by: Giteabot <teabot@gitea.io>

+# Debian Packages Repository
+
+Publish [Debian](https://www.debian.org/distrib/packages) packages for your user or organization.
+
+**Table of Contents**
+
+{{< toc >}}
+
+## Requirements
+
+To work with the Debian registry, you need to use a HTTP client like `curl` to upload and a package manager like `apt` to consume packages.
+
+The following examples use `apt`.
+
+## Configuring the package registry
+
+To register the Debian registry add the url to the list of known apt sources:
+
+```shell
+echo "deb https://gitea.example.com/api/packages/{owner}/debian {distribution} {component}" | sudo tee -a /etc/apt/sources.list.d/gitea.list
+```
+
+| Placeholder    | Description |
+| -------------- | ----------- |
+| `owner`        | The owner of the package. |
+| `distribution` | The distribution to use. |
+| `component`    | The component to use. |
+
+If the registry is private, provide credentials in the url. You can use a password or a [personal access token]({{< relref "doc/development/api-usage.en-us.md#authentication" >}}):
+
+```shell
+echo "deb https://{username}:{your_password_or_token}@gitea.example.com/api/packages/{owner}/debian {distribution} {component}" | sudo tee -a /etc/apt/sources.list.d/gitea.list
+```
+
+The Debian registry files are signed with a PGP key which must be known to apt:
+
+```shell
+sudo curl https://gitea.example.com/api/packages/{owner}/debian/repository.key -o /etc/apt/trusted.gpg.d/gitea-{owner}.asc
+```
+
+Afterwards update the local package index:
+
+```shell
+apt update
+```
+
+## Publish a package
+
+To publish a Debian package (`*.deb`), perform a HTTP `PUT` operation with the package content in the request body.
+
+```
+PUT https://gitea.example.com/api/packages/{owner}/debian/pool/{distribution}/{component}/upload
+```
+
+| Parameter      | Description |
+| -------------- | ----------- |
+| `owner`        | The owner of the package. |
+| `distribution` | The distribution may match the release name of the OS, ex: `bionic`. |
+| `component`    | The component can be used to group packages or just `main` or similar. |
+
+Example request using HTTP Basic authentication:
+
+```shell
+curl --user your_username:your_password_or_token \
+     --upload-file path/to/file.deb \
+     https://gitea.example.com/api/packages/testuser/debian/pool/bionic/main/upload
+```
+
+If you are using 2FA or OAuth use a [personal access token]({{< relref "doc/development/api-usage.en-us.md#authentication" >}}) instead of the password.
+You cannot publish a file with the same name twice to a package. You must delete the existing package version first.
+
+The server reponds with the following HTTP Status codes.
+
+| HTTP Status Code  | Meaning |
+| ----------------- | ------- |
+| `201 Created`     | The package has been published. |
+| `400 Bad Request` | The package name, version, distribution, component or architecture are invalid. |
+| `409 Conflict`    | A package file with the same combination of parameters exists already. |
+
+## Delete a package
+
+To delete a Debian package perform a HTTP `DELETE` operation. This will delete the package version too if there is no file left.
+
+```
+DELETE https://gitea.example.com/api/packages/{owner}/debian/pool/{distribution}/{component}/{package_name}/{package_version}/{architecture}
+```
+
+| Parameter         | Description |
+| ----------------- | ----------- |
+| `owner`           | The owner of the package. |
+| `package_name`    | The package name. |
+| `package_version` | The package version. |
+| `distribution`    | The package distribution. |
+| `component`       | The package component. |
+| `architecture`    | The package architecture. |
+
+Example request using HTTP Basic authentication:
+
+```shell
+curl --user your_username:your_token_or_password -X DELETE \
+     https://gitea.example.com/api/packages/testuser/debian/pools/bionic/main/test-package/1.0.0/amd64
+```
+
+The server reponds with the following HTTP Status codes.
+
+| HTTP Status Code  | Meaning |
+| ----------------- | ------- |
+| `204 No Content`  | Success |
+| `404 Not Found`   | The package or file was not found. |
+
+## Install a package
+
+To install a package from the Debian registry, execute the following commands:
+
+```shell
+# use latest version
+apt install {package_name}
+# use specific version
+apt install {package_name}={package_version}
+```
