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.

+# Prerequisites
+
+The following changes are made in C:\gitea\custom\conf\app.ini:
+
+```
+RUN_USER = COMPUTERNAME$
+```
+
+Sets Gitea to run as the local system user.
+
+COMPUTERNAME is whatever the response is from `echo %COMPUTERNAME%` on the command line. If the response is `USER-PC` then `RUN_USER = USER-PC$`
+
+## Use absolute paths
+
+If you use SQLite3, change the `PATH` to include the full path:
+
+```
+[database]
+PATH     = c:/gitea/data/gitea.db
+```
+
+# Register as a Windows Service
+
+To register Gitea as a Windows service, open a command prompt (cmd) as an Administrator,
+then run the following command:
+
+```
+sc.exe create gitea start= auto binPath= "\"C:\gitea\gitea.exe\" web --config \"C:\gitea\custom\conf\app.ini\""
+```
+
+Do not forget to replace `C:\gitea` with the correct Gitea directory.
+
+Open "Windows Services", search for the service named "gitea", right-click it and click on
+"Run". If everything is OK, Gitea will be reachable on `http://localhost:3000` (or the port
+that was configured).
+
+## Adding startup dependencies
+
+To add a startup dependency to the Gitea Windows service (eg Mysql, Mariadb), as an Administrator, then run the following command:
+
+```
+sc.exe config gitea depend= mariadb
+```
+
+This will ensure that when the Windows machine restarts, the automatic starting of Gitea is postponed until the database is ready and thus mitigate failed startups.
+
+## Unregister as a service
+
+To unregister Gitea as a service, open a command prompt (cmd) as an Administrator and run:
+
+```
+sc.exe delete gitea
+```
