Support Playwright's test runner

[jasonkuhrt]

Thanks @KATT, any research you can already share would be great.

Questions I have:

1. Are the hooks the same as Jest?
   • beforeAll / afterAll
   • beforeEach / afterEach
2. Are the hooks accessed globally? If not, how? What is their scope(s)? E.g. does a test instance need to be passed? A test suite instance? Etc.
3. Does PW have its own concept of composable context already? If so how does it work? Once understood, we can then understood if Konn augments, replaces, or co-exists with that system.
