scripts: requirements: bump nrf-regtool to 9.1.0

Added
* CTRLSEL is now set appropriately for the SPIS121 pins.

Updated
* NCSDK-33140: DPPI.LINK configuration is now skipped when processing
  the 'dppic130' devicetree node. This enables the DPPI driver to use
  both 'source-channels' and 'sink-channels' properties on it without
  causing a conflict.
