Django Integration complex url regex pattern cleanup

[PeterW-LWL]

Problem Statement

When using pythons sentry_sdk with Django and DjangoCMS using the default configuration for the DjangoIntegration I get a transactions {slug},w/]+)/.
This comes from the complex regex '^(?P<slug>[$\\-_.+!*(),\\w//]+)/$' which comes from DjangoCMS urls.py constants.py.

I expect even a complex regex like the above to get cleaned to just /{slug}/

Solution Brainstorm

Improve the regex filter in

sentry-python/sentry_sdk/integrations/django/transactions.py

Line 48 in 9857bc9

def _simplify(self, pattern):

Maybe even add a spezial case for this complex regex from DjangoCMS.
