Fix Sphinx configuration post-update (#5588)

Adjust Sphinx configuration and release script

Changes:

- Update `source_suffix` in docs/conf.py to use dict format as required
by newer Sphinx
  versions
- Fix typo in theme config: `pygment_light_style` ->
`pygments_light_style`
- Improve release script to handle Sphinx intersphinx output formatting:
  - Replace tabs with spaces for consistent parsing
  - Add reference to sphinx.ext.intersphinx command in docstring
  - Update line parsing to match space-indented format
- Restructure CI workflow to ensure relevant dependencies are installed
and changelog formatting is tested.

These changes ensure compatibility with newer Sphinx versions and
improve the robustness
of the release script's reference parsing.

Edit:

While working on this PR GitHub decided to upgrade their linux/ubuntu
runners with `Ubuntu 24.04`. Ubuntu upgrades are the worst: imagine not
updating your system for 3 years and then suddenly upgrading
**everything** to the most recent versions. At which point you start
realizing that the final **S** in their **LTS** means __Suffering__
instead of __Support__.

We use just a few system dependencies in our builds and as expected,
things broke:
* `libcairo2-dev` now needs to be installed for pygobject.
* `pandoc` `rst` -> `markdown` conversion output has changed
* Completion tests are unhappy about `bash` / `bash-completion` upgrade,
and I could not figure out why so I'm just `xfail`ing that test in CI.
