**Backport:** https://codeberg.org/forgejo/forgejo/pulls/7720
In order to improve the security of the Forgejo infrastructure the next-digest repository was moved to a private instance.
## Testing
- After the merge, trigger a mirror to build a new v12.0-test release
- Verify in experimental that the workflows works as expected
- Verify v12.next.forgejo.org is upgraded with the latest commit
- Once the test completes
- Tag for backport to v11 & v7
- Manual backport to v7 because it conflicts
