fix(quart): Skip quart-flask-patch and adjust error test for quart>=0.23 (#7320)

quart-flask-patch is incompatible with quart>=0.23 due to RequestContext
changes, so pin its dependency to <0.23 and skip the patch test above
that version.

Also update test_error_in_errorhandler: since 0.23 (db05772), Quart runs
request handling inside an asyncio.TaskGroup, so exceptions propagate
wrapped in an ExceptionGroup instead of bare.

Fixes PY-2754
Fixes #7305
