BUR #21060 has been approved by @nonamethanks.
rename counter_strike:_global_offensive -> counter-strike_2
create alias counter-strike:_global_offensive -> counter-strike_2
Reason for rename: missing hyphen
Reason for alias: CS2 is the same game as CS:GO but with FEWER characters/maps/weapons and doesn't even have the distinction that Overwatch 1/Overwatch 2 have. While eventually CS2 will get new characters/maps/weapons, this distinction is not at all important. It also doesn't matter for posts specifically referencing official key art like post #6210256, post #5689975, and anything else that looks specifically CS:GOey. CS:GO all but no longer exists, so any future art that is specifically the newer games is automatically presumed to be of CS2.
