Backport #28205 by @CodeShakingSheep
In the [docs for email
setup](https://docs.gitea.com/administration/email-setup)
`mailer.IS_TLS_ENABLED` is mentioned which was replaced by
`mailer.PROTOCOL` in release 1.18.0 according to
https://blog.gitea.com/release-of-1.18.0/ . This change wasn't reflected
in the docs for email setup. I just replaced the deprecated mailer
setting.

The setting `MAILER_TYPE` is deprecated.
According to the config cheat sheet, it should be `PROTOCOL`.

This PR cleans up the docs in a way to make them simpler to ingest by
our [docs repo](https://gitea.com/gitea/gitea-docusaurus).
1. It includes all of the sed invocations our ingestion did, removing
the need to do it at build time.
2. It replaces the shortcode variable replacement method with
`@variable@` style, simply for easier sed invocations when required.
3. It removes unused files and moves the docs up a level as cleanup.
