[v2,06/16] refs: refactor `resolve_gitlink_ref()` to accept a repository

Commit Message

Patrick Steinhardt May 17, 2024, 8:18 a.m. UTC

In `resolve_gitlink_ref()` we implicitly rely on `the_repository` to
look up the submodule ref store. Now that we can look up submodule ref
stores for arbitrary repositories we can improve this function to
instead accept a repository as parameter for which we want to resolve
the gitlink.

Do so and adjust callers accordingly.
