BUR #19378 has been approved by @nonamethanks.
rename metal_gear_solid:_ground_zeroes -> metal_gear_solid_v:_ground_zeroes
The game may have been announced as Metal Gear Solid: Ground Zeroes back in 2012, but between then and its release in 2014, it changed to Metal Gear Solid V: Ground Zeroes. The fact that the tag on Danbooru wasn't changed accordingly is incredibly odd, but better late than never. It might also be worth creating a BUR after this that has either Ground Zeroes imply The Phantom Pain, or having both imply a Metal Gear Solid V tag that encompasses both, because the current copytag situation for Ground Zeroes' posts is a mess.
