async_ssl / websocket.2.9 need an upper bound somewhere

Latest opam repository fails to combine websocket and async_ssl out of the box:

This is causing the docs.mirage.io build to fail, see https://hub.docker.com/r/unikernel/mirage/builds/bychhogn7quqyayxsnmh6mj/

Yep, indeed, I always test on janestreet bleeding edge. Will do, thanks!

I'll make a release when conduit/cohttp new flavour are released in opam.

@vbmithr nudge (the new jbuilder-built cohttp and conduit packages are on opam.)

Closing since this has been fixed a long time ago.
