MacOS ARM wheel OpenMP version may default to x86 instead of ARM

[mlxd]

It may be possible that the libomp binary installed from Brew on MacOS runners does not respect the target architecture of the machine.

When I tried to pass the tests with my Mac (ARM) I got the following message

Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
