[CI][Github] Bump Windows Container to Server 2022

This patch bumps the windows CI container to windows server 2022 from
windows server 2019. This is necessary as Github has sunsetted support
for sever 2019, so we cannot build the container through GHA without
updating. Using more recent versions is just good practice anyways.

This will not roll out immediately and we'll have to make some TF
changes to get deployed, but some additional validation first will be
good anyways.
