Improve readability of 'not callable using argument types' error message II

[ryuukk]

This is continuation of #16045

I think it could be further improved btw, but i don't like how getParamError is its own thing, i can't put a 2 line and change colors to display something like:

myfunction(string aa, int bb)   <-- in red
                      ^^^^^^    <-- cursor

This would be 100x more readable, and remove the need of the suplemental error messages

I have used make test AUTO_UPDATE=1 and looks like it incorrectly put my own paths.. how to fix that?

What is the proper way to automate updating the tests?

I'm having trouble understanding why opAssign is relevant for this error message.

That is the correct way, however, this PR suffers from the same problem described here: #16045 (comment) .
