Build Isograph for Windows

[rbalicki2]

• in ci.yml, Windows is disabled:

        # - target: x86_64-pc-windows-msvc
        #   os: windows-latest
        #   build-name: isograph_cli.exe
        #   artifact-name: isograph_cli-bin-win-x64

• If this is enabled, we get the following error:

  
  error: failed to get `intern` as a dependency of package `common_lang_types v0.0.4 (D:\a\isograph\isograph\crates\common_lang_types)`

Caused by: failed to load source for dependency intern

Caused by: Unable to update https://github.com/facebook/relay.git#f53a93272a1d756c60de795090fe70ca9532bb67

This might be easy to investigate and fix! The Relay compiler also uses intern, and the build step is very similar: https://github.com/facebook/relay/blob/main/.github/workflows/ci.yml

Thank you!
