Commit 31abfdda6527 (docs: Deprecate use of Sphinx < 2.4.x) in 6.2 added a warning that support for older versions of Sphinx would be going away. There have been no complaints, so the time has come.

2023-11-17docs: remove .toc-title classVegard Nossum
The "toc-title" class was introduced in commit ef88f10eb877 ("[media] doc-rst: backward compatibility with older Sphinx versions") as a workaround for Sphinx versions older than 1.4.x. However, these old versions have been deprecated since commit 31abfdda6527 ("docs: Deprecate use of Sphinx < 2.4.x"). Having now changed all the toc-title users to use the :caption: attribute, we can also remove the custom style. Note that the toc-title class is separate from the "kernel-toc" logic that was introduced in commit c404f5d4f099 ("docs: Add more information to the HTML sidebar").
