torch.zeros can not pass shape as keyword argument

[thomasjpfan]

import array_api_compat
import torch

x = torch.asarray([1.0, 2.0, 3.0])
xp = array_api_compat.get_namespace(x)
xp.zeros(shape=(8, 4))
# TypeError: zeros() missing 1 required positional arguments: "size"

Indeed, shape isn't positional-only so that will need some mapping from shape to size.

This is something I would have expected the test suite to catch. @honno

Either way, the fix here is easy. We just need to add a wrapper for zeros using the spec signature.
