py-qt5: update to 5.15.7.

v5.15.7 6th June 2022
  - Refactored the draw methods of QPainter to accept sip.array objects of
    appropriate types.  Such arrays, once initialised, can be used very
    efficiently as they do not require repeated conversion from the usual
    Python collection types.
  - Added the missing QBluetoothUuid constructors.
  - PyQt5-sip v12.11 is now required to enable support for sip.array.
  - Bug fixes.

v5.15.6 24th October 2021
  - Bug fixes.
