Add Regata to gaming

also add ChimeraOS because i've seen it enough - Gaming (based on Arch)

It doesn't have a DistroWatch page but I'm guessing that's because it's name conflicts with Chimera Linux.

add Drauger OS to show a Gaming distro based on Ubuntu. Now we have gamng distros from all the major upstreams.
