fix: resolve all untested and missing bios across platforms

Batocera: fix sc3000.rom md5 (no dump matches upstream hash),
remove erroneous bk0010.zip mame entries (upstream confirmed
mame needs no bios for bk), add PSP2UPDAT.PUP correct version.
Recalbox: add MSX2R2.ROM from blueMSX v2.82.
RetroDECK: fix stale peribox_ev/gen.zip md5 hashes.

Regenerate database, manifests, readme.
