Add a Step in Scenario filter

# Add a Step in Scenario filter

## Context

Currently, in the Executions screen, a user can filter with a Scenario's name or a Failed Step content. But there is no way to search for a specific step in a scenario which don't failed.

## Expected

Add a `STEP IN SCENARIO` filter which will filter over all scenario with this step, failed one or not.

Start at the Executions screen and trace the existing Scenario-name and Failed-Step filtering behavior. Add the requested STEP IN SCENARIO filter, then verify that it finds scenarios containing the selected step whether that step failed or not.
