This field was added in 3.12, it was never documented and is not intended for
external usage. (Contributed by Irit Katriel in :gh:`105481`.)

* Removed ``opcode.is_pseudo``, ``opcode.MIN_PSEUDO_OPCODE`` and
``opcode.MAX_PSEUDO_OPCODE``, which were added in 3.12, were never
documented or exposed through ``dis``, and were not intended to be
used externally.
