[Keymap] Minor userspace and Quefrency keymap fixes (#6134)

* Fix typo for RGBLIGHT config values

It doesn't make a difference right now since these are the defaults in
rgblight.h (which I'm just setting explicitly since some of the keyboard
configs change these defaults). However, I'd rather be explicit, so
fixing my typo. :)

* Remove mouse keys layer from Quefrency keymap

It's a fun idea, but I never use it in practice.
