CI stuck

[infinisil]

For some reason the build & deploy CI action doesn't complete for PRs anymore since like a couple days ago:

This currently affects:

• callpackage -> callPackage #931
• dynamically generate Nix manual version overview #863

Re-triggering CI by pushing doesn't fix it, however when I tried it for the first PR above, the CI action ran, but for the wrong commit.. https://github.com/NixOS/nix.dev/actions/runs/8175990939

This seems to be caused by #906

Revert: #933
