feat: use python3.11+ for cibuildwheel driver (#1912)

* chore: use SPEC 0 schedule for cibuildwheel

* remove support for {python} and {pip} in commands

* Remove specific Python versions from the update-dependencies job

The requirements pinning is done by uv now, so we don't need to
run the versions of Python to do the pinning anymore.
