[issue46431] Trouble subclassing ExceptionGroup

[Irit Katriel]

This is the fix:

-    if (!PyArg_ParseTuple(args, "UO", &message, &exceptions)) {
+    if (!PyArg_ParseTuple(args,
+                          "UO:BaseExceptionGroup.__new__",
+                          &message,
+                          &exceptions)) {


Then we get

TypeError: BaseExceptionGroup.__new__() takes exactly 2 arguments (1 given)
