How to downgrade to a previous version of MKdocs Material

Thanks to @kamilkrzyskow for answering this here #5761 (reply in thread)

I'm making it its own thread so it's easier for people to find in the future.

As for "downgrading" I think you want to install a previous version of mkdocs-material, right? You can do that via pip install mkdocs-material==9.1.0 where you specify the version, you can also add the --force-reinstall option to make sure everything is "freshly installed"

Upgrading, for reference: https://squidfunk.github.io/mkdocs-material/upgrade/
