Remove "Success Criteria" section from preview of the test collection form

Remove the "Success Criteria" section from the preview of the test output collection form.

Similar to the reports and single page view of the test plan in the app, we need to remove the following content from the collection form:

Success Criteria

To pass this test, JAWS needs to meet all the following assertions when each specified command is executed:

1. Role 'alert' is conveyed
2. Text 'Hello' is conveyed
3. JAWS switched from virtual cursor active to PC cursor active

We have removed the concept of passing a complete test; we pass/fail individual assertions but at the level of a test, we simply track the number/percentage of passing and failing assertions of each priority, so this content is no longer relevant.
