Describe the incorrect/future/missing documentation

The rendered page for PinnedMemoryResource.allocate is a single sentence. It does not say what the required keyword-only stream argument must be, what the method returns, or that the method raises RuntimeError when the device does not support the requested host memory pool. The one-line docstring on the override in cuda_core/cuda/core/_memory/_pinned_memory_resource.pyx is all autodoc has to render.

from cuda.core import PinnedMemoryResource

doc = PinnedMemoryResource.allocate.__doc__
print(doc)
print("documents the 'stream' parameter:", "stream :" in doc)
print("documents a return value:", "Returns" in doc)

PinnedMemoryResource.allocate(self, size_t size, *, stream: Stream | GraphBuilder) -> Buffer

Allocate a host-pinned buffer asynchronously on the supplied stream.
documents the 'stream' parameter: False
documents a return value: False

Expected: the page states that stream is required and has no default, what allocate returns, and that it raises RuntimeError on a device without the required host memory pool support. Either the full numpydoc body or a cross-reference to the base class would fill the gap, and both shapes are already used elsewhere in cuda.core.

If this is a correction, please provide a link to the incorrect documentation. If this is a new documentation request, please link to where you have looked.
