Some child classes inherit from both their parent and grandparent, causing "Cannot create consistent method ordering" error

[Road-hog123]

bl_operators/bone_selection_sets/__init__.pyi:

class POSE_OT_selection_set_copy(_PoseModeOnlyMixin, _NeedSelSetMixin)

The class should only inherit from the latter, as in the source scripts/startup/bl_operators/bone_selection_sets.py:

class _PoseModeOnlyMixin
class _NeedSelSetMixin(_PoseModeOnlyMixin)
class POSE_OT_selection_set_copy(_NeedSelSetMixin, Operator)

This issue is now fixed.

The error is resolved, but I'm now seeing the child inheriting only from the grandparent instead of the parent:

class POSE_OT_selection_set_copy(_PoseModeOnlyMixin, bpy.types.Operator)

This is a trivial bug. Fixed now.
