This makes it much nicer to use `BrowserType` because it no longer has a template.
Technically a breaking change because of the rare edge case where someone used their own non-browser type inside the template, but I don't consider that intended behavior and think this is fine.
New folio changed the JSON report, so we have to keep with the changes.
The most notable changes:
- there are no parameters any more. We recreate these as `testInfo.data`
arguments that are saved under test result's data.
- `test.runs` are renamed into `test.results`
I didn't find other changes so far - let's see if this works in the
cloud!
