[issue21577] Help for ImportError should show a more useful signature.

[Terry J. Reedy]

Terry J. Reedy added the comment:

Your example in #21578 suggests that **kwargs should be deleted.
*args is right.
>>> ImportError(3, 'a')
ImportError(3, 'a')

Should not this be fixed by ArgClinic conversion, and is not there an issue for that for exceptions?
