waitUntil page should link to waitUntil API doc and/or demonstrate use of the timeout param #565

Thanks for pytest-qt, it is a fantastic plugin. 😊

This is mostly a to-do-eventually for me, but writing it down in case someone else can pick it up earlier.

I was wanting to figure out whether waitUntil had a timeout parameter, but the top result on DDG is the waitUntil tutorial/demo page (source), which does not use the timeout= kwarg and does not link out to the API reference page (source).

Not a big deal, but either of those would have saved me a search. 😊

Thanks again!
