Release TODOs

[LecrisUT]

A few notes about tasks that should be resolved before release:

• Determine versions of packages to be released
• Organize tests and configure optional-dependencies
• Add releaser CD with manual trigger and test them locally in a fork
• Distribute the full sdist
• Move jupyter_config to be a sub-package?
• Update the documentation based on changes in
  General reorganization and modernization of the repository #1140
• Update the Menu and JupyterLab config screenshots in the documentation
• Release jupytext==1.16.0rc0
• Make sure that the jupytext downstream test in jupyter_server still passes
• Fix badge in top level README file

There might be more tasks that need to be added, but didn't get around to check everything. Other nice-to-haves:

• Add changelog to docs and maybe automate with .github/release.yaml?
• Revisit CI tools, what to keep, what to modernize
• Add Fedora CI so we have better understanding if something gets broken with packaging, dependencies etc.

@LecrisUT , I am thinking of releasing Jupytext 1.16.0 in the coming days. Are you fine with the packaging and the CI as they are currently? Thanks!

Minor comments:

• You need to add the step test-unit-functional-integration in dependencies for build step
• Could you update publish workflow to include new step_test_unit_functional.yml and step_tests-ui.yml steps? And also update dependencies accordingly.

Cheers!

Thanks @mahendrapaipuri ! I will be doing as you suggest at #1179.

Sorry for responding late, yeah most issues are resolved, I will open a PR with some minor changes soon which do not affect the packaging or release (it would not require a new release)
