Fix Python 3.12 CI

[flying-sheep]

The runner 20250209.1.0 with Ubuntu 24.04.1 (maybe others) might have problems.

First installing the build Python package into /opt/hostedtoolcache/Python/3.12.9/x64/lib/python3.12/site-packages didn’t result in /opt/hostedtoolcache/Python/3.12.9/x64/lib/python3.12/bin/python being able to import it, then bypassing that (by using uv tool install), a later step failed in the same way (the package wasn’t importable).

$ pyproject-build --installer=uv --wheel
* Creating isolated environment: venv+uv...
* Using external uv from /opt/hostedtoolcache/uv/0.6.1/x86_64/uv
* Installing packages in isolated environment:
  - hatch-vcs
  - hatchling
* Getting build dependencies for wheel...
* Building wheel...
