GHC 9.14 compat: replace async with time in a test for haddock-project

the test was using async from hackage as an exmaple global package.
Currently, async has a too restrictive upper bound on base. It'll be
more robust to rely on a boot package instead. Ideally we'd not rely on
anything from Hackage in tests, but that's an issue for another day.

Also, disable haddock-project on older Windows

It fails for an unknown reason; possibly the output is in the wrong
place compared to where the test looks, but tooling gets it right.
