Many Sphinx plugins now require Sphinx 5+ ([1], [2], and more), so sphinx 4.5 isn't usable as the requirements in sphinx itself are not pinned so you end up with a broken setup with errors such as: sphinx.errors.VersionRequirementError: The sphinxcontrib.serializinghtml extension used by this project needs at least Sphinx v5.0; it therefore cannot be built with this version. There's a sufficient number of plugins that manually pinning them all is tedious, so upgrade the documentation to Sphinx 5 (and the corresponding RTD theme). Also remove sphinx-copybutton, as this extension is unused.
