test(flaky): skip CodeCatalyst Inactivity Message test.

[Hweinstock]

Problem

Resolving #6213

Solution

• skip the test.
• This is low risk because:
  • the test above it tests very similar behavior.
  • a missing warning message not appearing is low risk.
  • codecatalyst users is aparently 0 anyway.

---

• 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.
