Wrong number of arguments in sipIsPyMethod

[Antonio Rojas]

Trying to compile krita with 6.8.0 produces multiple errors such as 

/build/krita/src/build/plugins/extensions/pykrita/sip/_tmp/krita/sipkritapart0.cpp:26826:28: error: too few arguments to function
26826 |     sipMeth = sipIsPyMethod(&sipGILState, &sipPyMethods[15], SIP_NULLPTR, sipName_actionEvent);

And indeed is seems sipIsPyMethod expects five argumens

but the generator only provides four:
