Issue: azerothcore/wiki#1022

Is your feature request related to a problem? Please describe.
Not a problem, but many wiki entries for documentation when they are big, having a button or buttons to go to the start and end of the page might be a good idea.

For the instalation pages, refered at least for the windows in my To Do List azerothcore/wiki#1020 Adding Headers for the Instalation Pages (Windows, Linux, Mac) for easier navigation within the page

Allowing people to have an easier navigiation. We have Enough space on the side to havea following button or something, specially if we implement the collapsabe side navbar azerothcore/wiki#1021

At this time, I don't know any alternative.
