docs for tasty usage

[mwotton]

Describe the feature you’d like to be implemented

There are a few tricks necessary to get Tasty running well under ghciwatch, like the bubblewrap buffering trick noted in #317 , as well as using tasty-autocollect rather than tasty-discover (as changes in the generated file under tasty-discover are not picked up.)

I'm happy to write it up, but is there an appropriate place to put docs on integration with specific test-running suites?
