 - Added a migration step for api repositories to fix `mkdocs.yml` when the previous `mkdocstrings-python` v2 migration moved only `paths: ["src"]` under `handlers.python.options` but not `paths: ["py"]`.
 - Fixed runners for jobs that require Docker and where wrongly converted to `ubuntu-slim` in v0.15.0, changing them back to `ubuntu-24.04` to avoid Docker-related failures. The template and the migration script were both updated to reflect this change.
-- Added a migration step to remove the copilot review request from the Protect version branch protection rules.  This was also done by v0.15.0 i theory, but the migration step was wrong and didn't update it properly.
