Silence deprecation warning about np.float usage

[diptorupd]

The following deprecation warning is thrown when running dpex tests

To silence this warning, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.

dpnp gets rid of usage of deprecation type aliases since #1276. It should resolve the issue.
