[New-bugs-announce] [issue46155] Implement ExceptionGroup __new__

[Irit Katriel]

New submission from Irit Katriel <iritkatriel at gmail.com>:

Currently ExceptionGroup inherits __new__ from BaseExceptionGroup, it should have its own __new__ implementation which raises a TypeError if any contained exception is not an Exception subclass.
