In Blender 3.3 (1) the individual combine and separate color nodes were combined together into a single combine/separate color node. To ensure legacy addons still worked, the old nodes were left in Blender, but hidden from the Add menus. It has been nearly 3 years since that change was made, most if not all addons should have been updated by now. So this commit removes these hidden legacy nodes.
