repository: do not interpret all files as gitlinks in discovery When trying to find a discovery, we walk up the directory structure checking if there is a ".git" file or directory and, if so, check its validity. But in the case that we've got a ".git" file, we do not want to unconditionally assume that the file is in fact a ".git" file and treat it as such, as we would error out if it is not. Fix the issue by only treating a file as a gitlink file if it ends with "/.git". This allows users of the function to discover a repository by handing in any path contained inside of a git repository.
