Subject: [PATCH] Fix a11y standards violation in DBT DAG webview test.

- Add expectNoA11yViolations test case to dbt_dag_test.ts.
- Switch dbt_dag_test.ts to use catalyst/async instead of catalyst/fake_async to allow XHRs needed by a11y tester.
- Update BUILD file with a11y_tester dependency and karma_webdriver_plugin.
- Fix scrollable-region-focusable violation in shared workflow_graph scaffold component by adding tabindex="0" to the graph area article.
