python3-exceptiongroup: Update to version 1.2.0

- Updated from version 1.1.0 to 1.2.0
- Update of rootfile
- Changelog
    1.2.0
	    Added special monkeypatching if Apport has overridden sys.excepthook so it
	     will format exception groups correctly (PR by John Litborn)
	    Added a backport of contextlib.suppress() from Python 3.12.1 which also
	     handles suppressing exceptions inside exception groups
	    Fixed bare raise in a handler reraising the original naked exception rather
	     than an exception group which is what is raised when you do a raise in an
	     except* handler
    1.1.3
	    catch() now raises a TypeError if passed an async exception handler instead
	     of just giving a RuntimeWarning about the coroutine never being awaited.
	     (#66, PR by John Litborn)
	    Fixed plain raise statement in an exception handler callback to work like a
	     raise in an except* block
	    Fixed new exception group not being chained to the original exception when
	     raising an exception group from exceptions raised in handler callbacks
	    Fixed type annotations of the derive(), subgroup() and split() methods to
	     match the ones in typeshed
    1.1.2
	    Changed handling of exceptions in exception group handler callbacks to not
	     wrap a single exception in an exception group, as per CPython issue 103590
    1.1.1
	    Worked around CPython issue #98778, urllib.error.HTTPError(..., fp=None)
	     raises KeyError on unknown attribute access, on affected Python versions.
	     (PR by Zac Hatfield-Dodds)
