module: remove :tools rgb

This module has been deprecated for some time; it's too niche, too
trivial, and is mostly centered around a single hydra (official support
for which I'll be phasing out of Doom).

-Highlights color hex values and names with the color itself, and provides tools
-to easily modify color values or formats.

-
-/This module has no external requirements./
-
-* Usage
-=rainbow-mode= provides automatic highlighting to hex color codes, and in
-relevant modes, color names (e.g. html color names in =css-mode= or LaTeX color
-names in =latex-mode=)
-
-=kurecolor= provides commands to easily change the brightness, saturation, and
-hue of hex colors (and a useful hydra for this, if =:ui hydra= is enabled), as
-well as conversion between hex and css colors
-
-* Configuration
-=hl-line-mode= overrides the color highlighting of =rainbow-mode=, limiting the
-use of that plugin and on-site color changes using =kurecolor=. To automatically
-disable it only when =rainbow-mode= is active, you can add the following hook:
-
-#+begin_src emacs-lisp
-;; in $DOOMDIR/config.el
-(add-hook! 'rainbow-mode-hook
-  (hl-line-mode (if rainbow-mode -1 +1)))
-#+end_src
