CB/fix: Consider RepoPath symlinked for size calculation (!37)

- Currently Codeberg is manually symlinking specific `.git` repository to the Ceph file system. While Git seems to handle this correctly, Gitea's code doesn't take this into consideration. This patch will always check if the `.git` repository is symlinked and if it, return the correct folder(the one on Ceph storage).
