docs(example): add example configuration

added both a home-manager and 'minimal configuration'.
They can be built and testet in this repo via:
- nixos-generate-config --dir example/default # or example/home-manager
- nix build path:./example/default#nixosConfigurations.default.config.system.build.toplevel # or path:./example/home-manager#...

the flake.lock and hardeware-configuration is ignored to prevent accidental commitment of the hardware-configuration (and get the freshes packages when somebody might use these configs as templates

example/default/flake.nix
