Hi,

sagemath fails to build with Sphinx 7.1 and docutils 0.20, both of which
are currently available in experimental.

Relevant part (hopefully):
The full build log is available from:
http://qa-logs.debian.net/2023/07/30/exp/sagemath_9.5-6_unstable_sphinx-exp.log

Please see [1] for Sphinx changelog and [2] for Docutils changelog.

Also see [3] for the list of deprecated/removed APIs in Sphinx and possible
alternatives to them.

Some notable changes in Sphinx 6 and Sphinx 7:

- Sphinx no longer includes jquery.js and underscore.js by default.
  Please use python3-sphinxcontrib.jquery package if you are using a custom
  template and it still needs jquery.

- The setup.py build_sphinx command was removed. Please instead call
  sphinx-build or "python3 -m sphinx" directly.

- For packages using the extlinks extension, the caption should contain
  exactly one "%s" placeholder (if caption is not None).

In case you have questions, please Cc sphinx@packages.debian.org on reply.
