Hi @deirdresama , I'm from Microsoft and recently I'm working on improving Python ecosystem support for Windows on Arm.
So I updates the CI workflows to add support for Windows ARM64 build and release. Could you please help to review? Thanks.

Build matrix updates:

  • The cibw_arch value for the Windows build (os: windows-latest) now includes both AMD64 and ARM64, enabling builds for both architectures instead of just AMD64.

Verified that this works on ARM64. Ran the build-wheels job with CIBW_ARCHS: ARM64 on windows-latest.
