Failed to build documentation locally

I encounter an error when publishing documentation locally using mkdocs according to the CONTRIBUTING.md doc.

After installing the requirements-docs.txt, I run the mkdocs serve command, and there is an error says:

INFO     -  Building documentation...
ERROR    -  Config value: 'markdown_extensions'. Error: Failed loading extension "mdx_truly_sane_lists".
ERROR    -  Config value: 'plugins'. Error: The "mkdocstrings" plugin is not installed
Aborted with 2 Configuration Errors!

Here is my installed packages:

Start with CONTRIBUTING.md and requirements-docs.txt, then reproduce the failure by running mkdocs serve in the documentation setup. Check why the mdx_truly_sane_lists extension and mkdocstrings plugin cannot be loaded with the listed packages. Done means the documented local publishing workflow builds without these configuration errors.
