Additional option to NOT produce the possible step definitions for undefined steps

[jfstephe]

Is your feature request related to a problem? Please describe.

ATM when a step is undefined the step definition is autogenerated in the web page. When the step is meant to be undefined (because this is being run manually), then this makes the page quite noisy.

Describe the solution you'd like 2 options come to mind:

1. a config option so that the step definition is never generated in the browser
2. a toggle in the steps component that showed/hid this (I'd suggest default of off).
3. The accordion for a scenario could have child accordions for each step that can be expanded if that detail is needed.

3 is probably my preference but happy to follow your lead.

Describe alternatives you've considered Live with it!

Additional context I'm happy to raise a PR for this, if you could point me at the areas you think need to change.
