Support catching multiple exceptions introduced in pep654 in python 3.11

[Pierre-Sassoulas]

Current problem

This new syntax is wrongly detected as a syntax error right now

Desired solution

Handle the new syntax.

Additional context

Spitballing here, but likely want to look into the exception grouping to be handled for the broad-exception-raised / broad-exception-caught messages.
