Use the gitea api in the gitea renaming playbook

Previously we were hacking the gitea web ui to transfer repo ownership
and to rename repos within an org. We believe this was necessary because
there was no REST API ability to do this. Now we have the ability to do
this via the REST API and in addition a new Gitea release will break our
web ui hijacking.

Update the project renaming playbook to use the REST API as it is
simpler to use and should be more reliable over time as it is versioned.
