Reduce the number of "required" extensions/dependencies

[dviererbe]

This is a tracking issue for the discussion in Riga to reduce the number of "required" extensions/dependencies

Reasoning:
The Ubuntu packaging guide wants to create a .deb package out of the built html/epub/pdf files so that they can be consumed offline. Therefore every dependencies needs to be packaged.

Vendored dependencies that are included with the source are technically possible, but against the Debian Packaging philosophy/culture and therefore also problematic to get uploaded.

[dviererbe]

The goal for the 24.04 LTS Noble Numbat cycle is to have the Ubuntu Packaging Guide packaged for noble.

After that I would like to also have it in trusty, xenial, bionic, focal, jammy and Debian stable. The problem
here is that often enough the packages either do not exist or are ancient. Additionaly, it is unlikely that the SRU team will let us upgarde ancient packages. I think that I am fine with having vendorized dependencies for these packages. New packages should be no problem for the SRU team, but new packages have to be maintained by someone :/

Let's go over the required dependencies (note that I only list Ubuntu LTS series and Debian stable in the summaries):

I propose to make the following extensions optional:

• linkify-it-py (only needed by myst-parser)
• lxd-sphinx-extensions (we don't use that)
• myst-parser (we write everything from scratch, therefore we want one consistent format (reStructuredText))
• sphinx-notfound-page (see Extension notfound.extension is not needed #139)
• sphinx-tabs (not needed as sphinx-design provides tabs)
• sphinx-reredirects
• sphinxext-opengraph

Note: I think we still would enable sphinx-reredirects and sphinxext-opengraph in the repository for ReadTheDocs but disable them in the packaged version.

[ru-fu]

I see why you want to exclude some of the extensions.
But as discussed in Riga, we should have three levels for the extensions:

• required
• included by default (but can be excluded)
• optional/custom

The extensions you are listing should be included by default because we recommend to use them (and, for example, expect to have them available according to our the style guide), but we need a mechanism to be able to exclude them for special cases like yours.
