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.

In this pull request, the following changes are addressed:
- State user should create `config.yaml` before start container to avoid
errors.
- Provided instructions to deploy runners using docker compose.
If a user starts a runner using a Docker image without making additional
configurations, the [cache action](https://github.com/actions/cache)
will not work properly.
Therefore, add a section in the documentation that explains how to
configure the cache correctly.
