Unsilenced deprecations that are no longer triggered

no issue

- cleaned up the `deprecation-workflow.js` file by removing deprecations that are no longer being triggered by our test suite or general app usage (if they are still triggered in untested areas it will be useful to see the logs)
- updated usages of `{{gh-text-field}}` to use it's `shouldFocus` attribute rather than directly overriding it's `autofocus` computed property
