[ci] Fix window version to 2022

flutter engine's window build uses Window SDKs 10.0.22621.0.
`window-2025` runner in gitHub actions no longer supports the `10.0.22621.0` SDK.

I tried several actions to install `10.0.22621.0` SDK,
but encountered other errors. This issue need to more investigation.
