Problem

test sometimes fail on CI and the code path is no longer being used

2 failing
  1) recommendationHandler
       getRecommendations
         should call telemetry function that records a CodeWhisperer service invocation:
     Error: Test length exceeded max duration: 30 seconds
[No Pending UI Elements Found]
      at Timeout._onTimeout (/Users/runner/work/aws-toolkit-vscode/aws-toolkit-vscode/packages/core/src/test/setupUtil.ts:47:32)
      at listOnTimeout (node:internal/timers:588:17)
      at processTimers (node:internal/timers:523:7)

  2) editorContext
       buildListRecommendationRequest
         Should return expected fields for optOut, nextToken and reference config:
