This PR addresses the false positives that were reported for generic rich-check-effect functions. Example:

func GenericFunc[T any]() (*T, error) {
	var resp T
	if someCond {
		return nil, errors.New("some error")
	}
	return &resp, nil
}

func CallGenericFunc() {
        v, err := GenericFunc[int]()
	if err != nil {
		return
	}
	print(*v)  // FP reported here: unassigned variable `v` dereferenced
}

Currently we do not handle generic rich-check-effect function calls in NilAway. So as a temporary solution, we suppress reporting of errors related to generic rich-check-effect functions. Note that this does help suppress false positives, but it also means that we don't report true positives either. We should fix this in the future when we add support for generics in NilAway.
