Fix GH Actions job to run on Ubuntu 24.04 (#37063)

* docbuild: Run sphinx in venv, update python version

Pip cannot upgrade pip on Ubuntu 24.04. Instead create and use a venv to run
the sphinx job. Also bump Python version to 3.12.

* Post-review updates:

- do not update pip
- use a venv also in cancel_workflows_for_pr.yaml and protocol_compatibility.yaml
- bump python version where applicable
