Align librapidsmpf with the 26.10. release pins*
librapidsmpf is still pinned to 26.8.* while libkvikio, librmm, and rapidsmpf are on 26.10.*. Update this pin here and in the matching CUDA env files, or document why it intentionally lags behind.

Update depends_on_librapidsmpf in dependencies.yaml to 26.10.* and regenerate the derived files. The generated conda envs and python/libcudf_streaming/pyproject.toml still inherit librapidsmpf==26.8.*, so the release metadata is out of sync with the rest of the 26.10.* set.

Finish the 26.10 dependency bump.
A few RAPIDS pins are still on 26.8.*, which can leave generated envs and builds mixing release series:
