build(docs): update Python dependencies

Update the python dependencies for building the project's Sphinx
documentation. Sphinx plugins are updated to the latest version, while
Sphinx itself is only updated to 5.3.0 (latest 5.x.x revision) due to
sphinx-rtd-theme not supporting any higher (both require incompatible
versions of docutils). Myst-parser is also updated to the latest version
to prevent a docutils clash as well.

The effect of this is to bump certifi to version 2022.12.7 and wheel to
0.38.4 as suggested by dependabot.
