Cosmetic: some unicode fonts not found by grub

I’m running 4.1 and this could be already fixed (then - just skip), but on boot grub reports:

error: file ‘/EFI/qubes/fonts/unicode.pf2’ not found.

this is with grub2-2.04-2.x86_64 packages in Dom0.

It boots okay though. The unicode support in console is broken on fedora34 (at least I’ve got this on my non-Qubes laptop after upgrade to fedora-34 from 33, where I had correct unicode in console), so this grub issue may be an upstream problem also.
