Test depedencies fail to install on ARM64 Windows

[dlech]

We recently added bumble as a dependency to run integration tests. Unfortunately, it depends on a package (grpcio) that doesn't have a binary wheel for windows ARM64 and fails to compile from the source distribution package.

I'm not sure there is anything we can do about it other than wait. google/bumble#834

Although we might want to create a separate group in pyproject.toml so that installing integration test dependencies are separate from other test dependencies.
