Bump to py3.11 in the GH templates, not the action

These yaml files actually get copied into user repos and can already
pass an overridden python version into our action.

If we bump the defaults in the action, we need to introduce a new tag >
0.1 to avoid introducing a breaking change for anybody who is pinned to
0.1 (onto to mention anybody who isn't pinned at all).
