test(doc): remove all tabs during tests

[jpinkney-aws]

Problem

For some reason the chat tests have consistently failed after 0989414 was merged. There isn't really a clear reason why this should be the case. Testing to see if reverting them makes them unflaky

Solution

---

• Treat all work as PUBLIC. Private feature/x branches will not be squash-merged at release time.
• Your code changes must meet the guidelines in CONTRIBUTING.md.
• License: I confirm that my contribution is made under the terms of the Apache 2.0 license.
