pin gha ubuntu base image

🚀 Pull Request

Description

The default GHA runner latest base image for ubuntu has bumped from 22.04 to 24.04.

This causes issues as the libgl1-mesa-glx APT package is not available and is the source of image tests hanging and/or the GHA cache-apt-pkgs-action to fail.

Adopting best practice advice from the pyvista core developers to pin the base image version and watch the GHA runner-images announcements to migrate (bump base image version) as part of a controlled, rather than unexpected changes through the latest base image label.

Note that, using an explicit GHA base image version is akin to the explicit os version used within the .readthedocs.yml.
