Planning to retire mkdocs, python-mkdocs-redirects

Hi I'm planning to retire mkdocs and python-mkdocs-redirects the coming weekend. mkdocs is currently FTI in F37 and F38. The reason is incompatibility with python-markdown-3.4.x, which upstream will not address in the immediate future [1]. Given that mkdocs is a leaf package and no other package depends on it (except for its plugins), pip + virtualenv is the better choice for users. The only packages depending on mkdocs are python-mkdocs-redirects, and mkdocs-markdownextradata-plugin (cc @music). Thanks Sandro [1] https://github.com/mkdocs/mkdocs/issues/2892#issuecomment-1200518008
