BUR #61488 has been approved by @evazion.
rename hello_world. -> hello_world._(nitroplus)
rename hello_world -> hello_world_(2019_movie)
I don't think I need to explain why these qualifiers are necessary, it's only worth discussing what they should be. For the visual novel, I opted for Nitroplus as opposed to Nitro+ due to the copytag, but it could go either way, while for the movie I opted to include the year of release, since there are other movies in live-action called that, but it could also just be 'movie' if necessary.
