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.

# 迁移功能
完整迁移功能在Gitea 1.9.0版本中引入。它定义了两个接口用于支持从其他Git托管平台迁移存储库数据到Gitea或者在将来将Gitea数据迁移到其他Git托管平台。
目前已实现了从GitHub、GitLab和其他Gitea实例的迁移。
首先Gitea在包[modules/migration](https://github.com/go-gitea/gitea/tree/main/modules/migration)中定义了一些标准对象。它们是`Repository`、`Milestone`、`Release`、`ReleaseAsset`、`Label`、`Issue`、`Comment`、`PullRequest`、`Reaction`、`Review`、`ReviewComment`。
## 下载器接口
要从新的Git托管平台迁移需要进行两个步骤的更新。
- 您应该实现一个`Downloader`,用于获取存储库信息。
- 您应该实现一个`DownloaderFactory`用于检测URL是否匹配并创建上述的`Downloader`。
- 您需要在`init()`中通过`RegisterDownloaderFactory`注册`DownloaderFactory`。
您可以在[downloader.go](https://github.com/go-gitea/gitea/blob/main/modules/migration/downloader.go)中找到这些接口。
## 上传器接口
目前,只实现了`GiteaLocalUploader`因此我们只能通过此Uploader将下载的数据保存到本地的Gitea实例。目前不支持其他上传器。
您可以在[uploader.go](https://github.com/go-gitea/gitea/blob/main/modules/migration/uploader.go)中找到这些接口。
