ci: Pin cp313t wheel builds to cibuildwheel v3

cibuildwheel v4 drops support for building 3.13t wheels. Switching from
using the pypa/cibuildwheel action to using `pip install` will let us
express the version constraint for this job and stop dependabot from
trying to update it to a version that can't work.
