feat: Searching for step text should return matching results

[jfstephe]

Summary of this PR

Currently it's not possible search manual test results by the step contents.

This has been resolved by adding a hidden column to the tables that can be searched, which contains all the step text of the scenario(s)/features(s). This is then, by default, included in the terms which can be searched.

Intended effect

This adds the ability to search manual test results by the step contents, but doesn't display the steps test.

How should this be manually tested?

Check the Filters work as expected, picking up the Steps as match values.
Normal regression testing.

Side effects

One strangeness was I had to put "width: 100%" on the HTML tables when hiding the steps text columns. I believe this is a bug in the js library being used.

Documentation

I believe this now works more like the user would expect.

NOTE: Related to #3448 (thanks for starting to address some of the issues!), I wasn't able to fully run the "mvnw clean verify" command successfully. It fails for me on jira related tests. I was able to build the parts that I've changed and test the app as best I can, but I think someone should give it a 'once over' at a minimum.
