Add non-free-firmware

[rclobus]

Helle Fréderic,

Would it be possible to add the non-free-firmware section (in addition to main)?
I'm currently preparing an update to live-build to use the new firmware section and Jenkins uses snapshot.notset.fr.
I have no need to go back in time to the moment that the new section was created.

With kind regards,
Roland Clobus

And the latest Jenkins results show that for bullseye both contrib and non-free need to be added as well.

Summary:

• bullseye: contrib, non-free
• bookworm, testing, sid: non-free-firmware
