Update consistency of <manager-IP>:<port> (#2117)

This is the same issue as the page "Try it out and vote". I have updated the consistency of format to be the same through all pages. (and I hope I do not overdo these small things, but I just like the ease of proposing changes to the documentation and I hope that it is getting better this way)
