android.yml run 116 (main push on 2534384e) failed the debug-APK
upload step with:
::error::@actions/artifact v2.0.0+, upload-artifact@v4+ and
download-artifact@v4+ are not currently supported on GHES.
Gitea Actions emulates GHES; the v2 backend used by upload-artifact
v4 isn't implemented there yet. Pinning to @v3 keeps the main-push
debug-APK channel working without affecting the tag-push release
path (which doesn't use this action).
