Locate error source of ExceptionGroup in Python shell

The Python shell recognizes the line containing a file path and
a line number when an exception is raised up to the top-level,
in order to locate the source of error.  It's supposed to
recognize the built-in ExceptionGroup as well.  (Bug#70653)
* lisp/progmodes/python.el (python-shell-compilation-regexp-alist):
Take the single leading vertical line into account.
* etc/NEWS: Announce this change.
