The original error message on the last line I have added to in
functionParameterArityMismatch.ts was
No overload expects 5 arguments, but overloads do exist that expect
either 4 or Infinity arguments.
even if we do not define a function that takes Infinity arguments.
This PR changes it to this:
Expected 0-6 arguments, but got 5 or more.
I feel it is still a bit strange but much more understandable.
