This commit updates the home-manager flake input to the 22.11 release
and creates additional support for the new homeManagerConfiguration
setup that is introduced there: Some arguments that were previously
in use, now need to be used inside the new modules argument (check
[here][hm-22.11-highlights] for more details).
Finally, the examples of using home-manager now declare explicitly the
stateVersion, since the 22.11 release makes this mandatory.
