Fix: Enable mdx_truly_sane_lists in mkdocs.yml

The build workflow installs the `mdx_truly_sane_lists` pip package, but the extension was not enabled in the `mkdocs.yml` configuration file.

This change enables the extension by uncommenting the relevant lines in `mkdocs.yml`, bringing the configuration in line with the build environment.
