Bump up Windows Server to version 2022 by default

Describe what you are trying to do

Hi,

Windows Server 2019 has reached the end date (Jan 9, 2024) of the mainstream support, while Antrea still uses Server 2019 in its official document and the CI environment. So it's time to bump up the support to Windows version to Server 2022.

• Update Windows Nodes in CI env to use Server 2022
• Update Antrea Agent Windows container image to use Server 2022 as a base #6290

Move this to milestone 2.2 because of BSOD issue when OVS extDriver running on Windows 2022, we need to wait OVS bugfix ready before update Windows Nodes in CI env to use Server 2022.

Windows CI has been upgraded to 2022, but it will be unavailable during CI migration according to #6698.
