Respect Gitlinks per Attached Repository

Hello dear community, in e.g. mkdocs-material there is nice feature: https://squidfunk.github.io/mkdocs-material/setup/adding-a-git-repository/#adding-a-git-repository

By simple config in yaml file:
```
repo_name: Trolololo
repo_url: https://somehost.com/Trololo
edit_uri: "edit/master/docs/"
```
will enable this:
By clicking you are jumping into the Repositroy to exact file.

When I use monorepo no links will be provided.

Please respect config per attached repository.

Start by tracing how attached repositories and their YAML configuration are read, then follow how MkDocs edit links are generated for monorepo pages. Done means each attached repository can provide its own repository and edit-path settings, with links reaching the exact documentation file; the issue does not name a file or test to run.
