Counter-Strike changes

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.

The bulk update request #21060 (forum #259348) has been approved by @nonamethanks.

BUR #38202 is pending approval.

remove alias counter-strike:_global_offensive -> counter-strike_2

Despite CSGO no longer existing, iconic scenes like the olofboost or other memorable moments are an integral part of the memory and culture of CSGO. It's unreasonable to lump all CSGO posts into CS2 just because of an update, when we can expect CS2 to have it's own moments to shine in the future.

I think that's silly pedantry, especially on a site for anime pictures. CS2 is still just an update for CSGO, the tag can function for both.

It should probably be even more like Overwatch and just have everything under "counter-strike". It's all the same universe and characters with very little distinction except for posts that are derivative of the games' unique branding. counter-strike online and counter-strike neo could possibly be left out.

This bulk update request is pending automatic rejection in 5 days.
