Outliner: Collection icon color tweaks

The icons originally chosen for the collection colors were selected
during development and had a few issues with contrast in the light
theme, and the gray color was not a good choice against the default gray
backgrounds.

The new colors are more readable in both default Blender themes. Gray
was replaced with pink.
