Create Screenplay binding for Playwright

[craigfowler]

Follow-on from #213. I want full support for Playwright from Screenplay.

I'm curious, why is this blocked/deferred?

For context, I'd love to set up a testing platform that combines TUnit (I'll use it for my unit tests but would love to use it for Screenplay tests as well for consistency & simplicity), Playwright, and CSF.Screenplay on .NET 10. I have no idea how much pain I'm going to be in for by doing that, but figured I'd ask. 😅
