Bug: Removed feature flag still referenced in test

The feature flag organizations:workflow-engine-single-process-metric-issues is being removed from the registry, but it's still referenced in tests/sentry/incidents/test_charts.py at line 184 via @with_feature("organizations:workflow-engine-single-process-metric-issues"). When this test runs, the Feature context manager will raise a ValueError with "Unregistered feature flag" because features.get() will throw FeatureNotRegistered for the now-unregistered flag. The test file needs to be updated to remove this decorator.

src/sentry/features/temporary.py#L542-L543

sentry/src/sentry/features/temporary.py

Lines 542 to 543 in 2f08b76

	# Enable dual writing for issue alert issues (see: alerts create issues)
	manager.add("organizations:workflow-engine-issue-alert-dual-write", OrganizationFeature, FeatureHandlerStrategy.FLAGPOLE, api_expose=False, default=True)
