Allow warp-3.3

Which is e.g. in Stackage nightly.

Looks like that servant-auth-client tests timeout with it. I don't know why, all help is welcome.

I was experimenting with bumping the dependencies on servant and servant-auth (to run them under GHC 8.10) and I noticed this issue and tried it (on GHC 8.8.3). I did not see the problem mentioned here where tests were timing out. They all passed fine (after I increased the file descriptor limit on OSX, see #113 ). Is it possible that the file-descriptor limit problem is also the cause of the above?

For reference, here's a record of what I ran and the results (OSX 1.15.5):

As an example you can see 9min to run tests (that should otherwise take 30s) here: https://github.com/haskell-servant/servant-auth/runs/1027581773?check_suite_focus=true

The good news is that github actions don't fail on no output, so we can allow warp-3.3 and defer this work to improve CI build times.
