fix(build): explicitly set up Python 3.12 to support Bikeshed v7#230
Merged
Conversation
Bikeshed v7 introduced a strict requirement for Python 3.12+. Because the default GitHub Actions `ubuntu-latest` runner uses an older version of Python by default, `pipx install 'bikeshed==7.*'` fails with a "no matching distribution found" error. This commit injects `actions/setup-python@v5` into the composite action directly before the toolchain setup step. This ensures `pipx` has the correct environment to install Bikeshed successfully, fixing widespread CI breakages across W3C/Explainer repositories. Fixes w3c#99
