`npsupport` does not work with `numpy>=2.0.0`

[junkmd]

I noticed that the tests for comtypes.npsupport fail when numpy==2.0.0 is installed.

ERROR: test_VT_I4_ndarray_enabled (test_npsupport.NumpySupportTestCase)

To avoid a situation where we can't develop other features until npsupport supports numpy==2.0.0, I will change the GHA workflow so that the numpy installed in the CI environment is a version lower than 2.0.0 for the time being.

I'm not particularly familiar with the use cases for npsupport, so I hope that community members who have a high priority for npsupport will fix it.
