chore: mark what the new profiles' installs bring

The profiles written for RetroBat and RetroPie were checked the same way: UZDoom, LZDoom, SRB2 and AdvanceMAME data ship with their releases, RetroPie installs the shareware Doom, Quake III and Wolfenstein data, the Aleph One scenarios and 4DOS beside the ports it builds, RetroBat installs Jynx's ROMs, and Recalbox's uae4all core comes without the AROS ROMs.
