PEP654 introduced exception groups andexcept* in python3.11
Link:https://peps.python.org/pep-0654/

Right now it is possible to parseexcept* with olderast.parse(..., feature_version=(3, 10)).
Example:

>>>importast>>>code='''... try:...   ...... except* Exception:...   ...... '''>>>>>>ast.parse(code)<ast.Moduleobjectat0x10c685410>>>>ast.parse(code,feature_version=(3,8))<ast.Moduleobjectat0x10c685280>>>>

Which is not correct.

But, unlike#96427 it is very simple to fix. And I belive it should be fixed.

I've already applied a patch and will send it shortly after :)
