Add integration tests to prove that web driver quirks are working

[craigfowler]

I have a suspicion (whilst testing Screenplay) that WebDriver Quirks might not be working correctly. I'd like to write an integration test in this library which creates two different local web drivers (how about Firefox & Chrome, which can run locally on Linux & Windows).

I can then invent some 'fake' quirks to give them (one for Chrome only, the other for Firefox only) and assert that each browser received the correct quirk.

I may also wish to switch the CI builds to Github Actions when I do this.
