test(e2e): stabilize Amazon Q feature development tests (#6520)

## Problem

Amazon Q feature dev e2e test was disabled due to flakiness. Issue:
#6513


## Solution

- Modified test prompt to prevent no change required scenarios that were
causing deadend.
- Add `getSelectedTab` function in `qTestingFramework` to access newly
created tab by quick action.


---

- 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](https://github.com/aws/aws-toolkit-vscode/blob/master/CONTRIBUTING.md#guidelines).
- License: I confirm that my contribution is made under the terms of the
