feat: add contributor credits to pack readme

Add MSX2J.rom (sha1: 0081ea0d25bc5cd8d70b60ad8cfdc7307812c0fd, size: 32768) to multiple install manifests and the RetroDECK bios list. Update generated timestamps and adjust total_files/total_size counts in batocera, lakka, recalbox, retroarch, retrobat, and retrodeck manifests. Also bump README verified file count and regenerate the auto-generated timestamp to reflect the new entry.
