Python bootstrap

[benoit74]

Fix #180

Changes:

• CI has been revisited with new jobs / stages
  • ⚠️ Trusted publishing must be setup on this repo
• pre-commit is ready to use
• use python 3.11 + bookworm (drop support for older Python versions)
• enhance documentation
• update Python and JS dependencies
  • except zimscraperlib which will be done later with #175 since probably more invasive)
  • except when not feasible due to other constraints
• migrate to hatch instead of setuptools
• fix issues raised by linter / type checker
  • add a load_mandatory_json util function which raises an error if file is not present or JSON is not valid (instead of returning None)
  • add a render_template util function which returns a string or returns an error (to circumvent various types returned by Jinja)
  • this might not be needed anymore once we will be able to update Jinja
• add dummy test (before more will come hopefully)

I just uploaded https://dev.library.kiwix.org/viewer#badminton_webm_2023-10/home.html which has been created by this new code.

I would like to test this on IE11 / old Safari to ensure there is no regression since I updated the webp polyfill, but I probably do not have it at home.
