fix(amazonq): Fix Quick Actions Test Suite

[laura-codess]

Problem

There were some CSS changes to the quick actions menu which caused the old test suite to break.

Solution

This change fixes the CSS to match the new quick actions menu, and rewrites the tests to utilize the current Quick Actions commands

• This pull request implements a feat or fix, so it must include a changelog entry (unless the fix is for an unreleased feature). Review the changelog guidelines.
  • Note: beta or "experiment" features that have active users should announce fixes in the changelog.
  • If this is not a feature or fix, use an appropriate type from the title guidelines. For example, telemetry-only changes should use the telemetry type.

Do you think we should fix the dismissOverlayIfPresent or is it not needed anymore?

[laura-codess]

Good catch, I think we should probably just delete the code for it until we find a better way to implement it, I'll make that change

could be worth adding a comment of why this is needed.
