ruby-ts-mode: Highlight variable assignments

Browse source 
* lisp/progmodes/ruby-ts-mode.el (ruby-ts--font-lock-settings):
Bring back the 'assignment' feature.
(ruby-ts-mode): Replace the unused 'variable' with 'assignment'.  Use
the level 3 for consistency with other ts modes.
Update the Commentary as well.
