Routing issue: vapor docs url without trailing '/' times out.

[marc-medley]

The vapor doc URLs https://docs.vapor.codes/2.0/ and https://docs.vapor.codes/3.0/ responds OK.

However, https://docs.vapor.codes/2.0 and https://docs.vapor.codes/3.0 timeout.

After the connections times out, then the URLs that timed out show as https://docs.vapor.codes:8080/2.0/ and https://docs.vapor.codes:8080/3.0/ in the browser navigaton bar.

So, my exiting vapor doc bookmarks (that used to work) needed to be updated with the appended /.

This seems to be fixed now
