feat: add home-manager directly in NixOS-95

For users that already use home-manager, this shouldn't change anything (they just have to pin the home-manager input to their own version).
However for users that currently do not use home-manager this will allow them to not care about it.

This way, home-manager will become an 'implementation detail'
