name: Publish to Modrinth

# Publishes the jars already attached to a Gitea release (built by the Release
# workflow) to Modrinth, one version per Minecraft version. Run it manually
# after smoke-testing the release. It doesn't rebuild anything, and versions
# already on Modrinth are skipped, so re-running is safe.
#
# Needs a MODRINTH_TOKEN repository secret: a Modrinth PAT with the
# "Create versions" scope.
