fix(ci): reclaim working-tree ownership after Crowdin Docker action

The crowdin/github-action runs inside a Docker container as root, so files
and directories it downloads are root-owned. When Crowdin creates a brand-new
locale folder (e.g. values-en-rGB/ under commons), the unprivileged runner
user in the peter-evans/create-pull-request step can't unlink files inside it,
so the branch checkout aborts with 'unable to unlink ... Permission denied'.

Add a chown step that reclaims ownership of the whole working tree after the
Crowdin action and before any git manipulation.
