The Container Images for Windows Server 2022 have been published, and
we can start building test images using them, so we can start adding
jobs for them.
The image versions for the e2e test images have been bumped in a previous
commit, but haven't been promoted yet. We don't need to bump them here.
We're starting with windows-servercore-cache and busybox images, since
they are needed for the other images the most.
A previous added LD_FLAGS for the go binary compilation, but it's not
defined for all images.
