add Microsoft.VisualStudio.2022.BuildTools installation (#9541)

## Description

We have been saying that installing Visual Studio is required to build
Warp. however, the whole thing isn't needed, just the MSVC Build Tools.
That is available through winget and we can easily automate that in the
script.

## Testing

This worked when setting up a dev env on a new Windows device.
