`vizia_plug::assets::register_noto_sans_light()` does not exist

The docs are outdated. I'm not doing a PR because I don't know if this was intentionally removed or what. Just wanted to let you know the docs still say to call that function when it doesn't exist.

For ViziaTheming::Custom and fn create_vizia_editor but could be more, that's just what I found from goto definition + search.

Thanks for letting me know. You’re right that the docs are wrong here and that function no longer exists. Will update it.
