Show summary report in checks and groups for K6

[Inculator]

While executing K6 scenarios, the summary also displays something like this :
█ Scenario: "AccountCreationScenario"

   █ Setup:

     █ Verify token generated correctly

       ✗ Exception raised "the body is null so we can't transform it to HTML - this likely was because of a request error getting the response"
        ↳  0% — ✓ 0 / ✗ 1

   █ Test:

     █ Set the current date to now

       ✗ expected response code is 'OK', got +0
        ↳  0% — ✓ 0 / ✗ 1

     █ Search a customer in CRD to check its existence

Any success or failure like this is not displayed in the HTML report checks tab or anywhere in the HTML report.
This is required in order to identify what has failed from the report itself when it is being delivered to servers.

If this block could be filled with the summary of failing steps, the report will be more complete.
