fix: name the 0.289 galaxy games bios galgames

MAME renamed the Galaxy Games BIOS root from galgbios to galgames in 0.288 (galgames.cpp:1301, listxml of 0.288 and 0.289). mame.yml and mamearcade.yml document 0.289 yet still listed galgbios.zip; mamearcade lacked galgames.zip, which mame.yml already had. The release profiles mame0258 and mame0278 keep galgbios.
