Bug Description
[Impact]
New upstream release; shim security update CVE-2022-28737
[Test plan]
https:/
[Where problems could occur]
Machines could become unbootable due to bugs as usual.
Key rotations that require newer kernels can't enforce newer kernels being on the system prior to updates resulting in unbootable systems if kernels are not available.
Requires the grub2-unsigned >= 2.04-1ubuntu47.4, >= 2.06-2ubuntu10 to be
published to security and on each machine first too. Maybe should add Breaks to those (though you can set 'latest' policy and it would require upcoming grub uploads, so not _entirely_ useful).
Also breaks fwupd.

I have verified so far:
1. shim -> grub -> shim -> grub netboot -> disk chainloading as MAAS does
2. fwupd on all releases in VM that it starts, and on real hardware updated my firwmare
Haven't tested mokutil yet, or chainloading to a different distro or windows.
