retry does not retry all exceptions

[martin-tarjanyi]

It looks like Kotest's retry block only retries assertion related errors and exceptions which exactly has Exception class. For example RuntimeException or NullPointerException are not retried. Is this intentional?

The documentation of the function says:

This will treat any Exception as a failure, along with [AssertionError].

e::class != config.exceptionClass &&

Should probably be instanceOf, I think you are right.

It doesn't need to be exactly Exception, but the class you passed.

I agree it should be Class and Subclasses.
