/kind cleanup

What needs cleanup:

Currently e2e tests and the default VM image code in CAPZ are still returning windows-2019 images, but these are deprecated and we've stopped publishing them.

We need to change a few variables to -2022 from -2019 and clean up any unit tests that break. But since we've had problems with this in the past (see #5192 and #4867), it's probably not going to just work and investigation will be needed.
