Checks

  • I have checked that this issue has not already been reported.
  • I have confirmed this bug exists on the latest version of Polars.

Reproducible example

I noticed that the implementation of the PyArrow Capsule interface in #17676 makes the requested_schema argument required, although the PyCapsule interface has this default to None

https://arrow.apache.org/docs/dev/format/CDataInterface/PyCapsuleInterface.html#arrow_c_stream__
