Docusaurus-ify (#26051)
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.

# Migration Features
Complete migrations were introduced in Gitea 1.9.0. It defines two interfaces to support migrating
repository data from other Git host platforms to Gitea or, in the future, migrating Gitea data to other Git host platforms.
Currently, migrations from GitHub, GitLab, and other Gitea instances are implemented.
First of all, Gitea defines some standard objects in packages [modules/migration](https://github.com/go-gitea/gitea/tree/main/modules/migration).
They are `Repository`, `Milestone`, `Release`, `ReleaseAsset`, `Label`, `Issue`, `Comment`, `PullRequest`, `Reaction`, `Review`, `ReviewComment`.
## Downloader Interfaces
To migrate from a new Git host platform, there are two steps to be updated.
- You should implement a `Downloader` which will be used to get repository information.
- You should implement a `DownloaderFactory` which will be used to detect if the URL matches and create the above `Downloader`.
- You'll need to register the `DownloaderFactory` via `RegisterDownloaderFactory` on `init()`.
You can find these interfaces in [downloader.go](https://github.com/go-gitea/gitea/blob/main/modules/migration/downloader.go).
## Uploader Interface
Currently, only a `GiteaLocalUploader` is implemented, so we only save downloaded
data via this `Uploader` to the local Gitea instance. Other uploaders are not supported at this time.
You can find these interfaces in [uploader.go](https://github.com/go-gitea/gitea/blob/main/modules/migration/uploader.go).
