rom.sh: support making pcsx-redux bios release

I also checked the copyright declarations in the
directory src/mips/openbios where the PCSX-Redux BIOS
is, gleaning all the copyright years: 2019-2024 at this
time.

The years will be updated as and when PCSX-Redux is
updated in lbmk. Their BIOS is under MIT so I made lbmk
generate an appropriate COPYING file alongside the binary,
containing:

Copyright (c) 2019-2024 PCSX-Redux authors

Along with the actual text of the MIT license. With all
of this, the PCSX-Redux BIOS can now be included in
Libreboot releases.

No actual tarball is created. The release script in lbmk
simply copies the bin/ directory to ../roms

I'm leaving the PCSX-Redux BIOS release uncompressed,
because, and this will sound patronising because that is
my precise intention: Windows users don't know how to do
anything. If I provide a tarball to Windows users, they
won't know what to do. Libreboot releases always go on rsync
mirrors, which also have HTTP servers with indexing enabled,
for browsing release files.

I mention Windows users, because most people who use the PCSX
Redux BIOS will probably use it on a PlayStation emulator, and
most emulator users are on Windows. I can't really be bothered
to provide it as a .zip archive, and it's only 512kb, so just
provide it uncompressed in Libreboot releases!

Releases were already possible under this scheme, so this
patch really just adds the COPYING file. It's simply a courtesy
to the PCSX-Redux developers, providing proper credit to them.
