Run tests on Ubuntu 22.04

[smoser]

I think that we originally used 20.04 due to a bug in 22.04. https://bugs.launchpad.net/bugs/1986692

That is fixed so we should be able to move to 22.04.

closing this for now because 22.04 runs significantly slower. Its not just 1 test, I saw this on multipe that I ran with it.

I collected the results below from the ''Boot test' output for this pr vs current tip

test	20.04	22.04	diff
mode=nvram
ib-noshim-allowed	42.08	74.14	32.06

The first thing I would dig on is if there is something in the ovmf firmware from 22.04 vs 20.04 that is causing the slowdown. That can be tested pretty easily by just publishing the 20.04 ovmf versions and downloading them rather than using the ones from the system (collect-firmwares does that).

I'm uploading the current result of 'collect-firmwares' running in a focal container here. focal-firmwares.tar.gz

This is pretty clearly the Jammy OVMF in one way or another. I'm running jammy locally and running the shell script below with 'true' and 'false' values for KVM.

Results (wall clock/"real") of the combined set of 8 tests in 8 threads look like:

kvm	mode	focal	jammy
true	efi-shell	16.495	24.291
true	nvram	31.886	37.588
false	efi-shell	48.175	82.063
false	nvram	74.986	121.952
