Refactor docs (#23752)
This was intended to be a small followup for
https://github.com/go-gitea/gitea/pull/23712, but...here we are.
1. Our docs currently use `slug` as the entire URL, which makes
refactoring tricky (see https://github.com/go-gitea/gitea/pull/23712).
Instead, this PR attempts to make future refactoring easier by using
slugs as an extension of the section. (Hugo terminology)
- What the above boils down to is this PR attempts to use directory
organization as URL management. e.g. `usage/comparison.en-us.md` ->
`en-us/usage/comparison/`, `usage/packages/overview.en-us.md` ->
`en-us/usage/packages/overview/`
- Technically we could even remove `slug`, as Hugo defaults to using
filename, however at least with this PR it means `slug` only needs to be
the name for the **current file** rather than an entire URL
2. This PR adds appropriate aliases (redirects) for pages, so anything
on the internet that links to our docs should hopefully not break.
3. A minor nit I've had for a while, renaming `seek-help` to `support`.
It's a minor thing, but `seek-help` has a strange connotation to it.
4. The commits are split such that you can review the first which is the
"actual" change, and the second is added redirects so that the first
doesn't break links elsewhere.

# Container Registry
Publish [Open Container Initiative ](https://opencontainers.org/ ) compliant images for your user or organization.
The container registry follows the OCI specs and supports all compatible images like [Docker ](https://www.docker.com/ ) and [Helm Charts ](https://helm.sh/ ).
## Requirements
To work with the Container registry, you can use the tools for your specific image type.
The following examples use the `docker` client.
## Login to the container registry
To push an image or if the image is in a private registry, you have to authenticate:
```shell
docker login gitea.example.com
```

If you are using 2FA or OAuth use a [personal access token ](development/api-usage.md#authentication ) instead of the password.

## Image naming convention
Images must follow this naming convention:
`{registry}/{owner}/{image}`
For example, these are all valid image names for the owner `testuser` :
`gitea.example.com/testuser/myimage`
`gitea.example.com/testuser/my-image`
`gitea.example.com/testuser/my/image`
**NOTE:** The registry only supports case-insensitive tag names. So `image:tag` and `image:Tag` get treated as the same image and tag.
## Push an image
Push an image by executing the following command:
```shell
docker push gitea.example.com/{owner}/{image}:{tag}
```
| Parameter | Description |
| ----------| ----------- |
| `owner` | The owner of the image. |
| `image` | The name of the image. |
| `tag` | The tag of the image. |
For example:
```shell
docker push gitea.example.com/testuser/myimage:latest
```
## Pull an image
Pull an image by executing the following command:
```shell
docker pull gitea.example.com/{owner}/{image}:{tag}
```
| Parameter | Description |
| ----------| ----------- |
| `owner` | The owner of the image. |
| `image` | The name of the image. |
| `tag` | The tag of the image. |
For example:
```shell
docker pull gitea.example.com/testuser/myimage:latest
```
