The wiki page should be presented more prominently

@mpenkov Thanks. The wiki page should (in my opinion) be presented more prominently.
I totally missed this benchmark page although I am using gensim for a while.

It doesn't look like https://radimrehurek.com/gensim/wiki.html is accessible anywhere from the top level documentation (and if it is, then it should be more obvious). I'm not sure of what the best place to link these docs is. It's definitely not a good fit for the gallery because it takes over 9 hours to run, according to itself.

Maybe it could also be renamed to https://radimrehurek.com/gensim/wikipedia.html
My first impression was, that this wiki(pedia) page is somehow similar two the Github wiki. This is a bit misleading.

How did you initially find this page, @jonaschn ?

[jonaschn]

Actually, not at all.
@dymil found this page and replaced the link to the online LDA paper (in #3141) which I already replaced previously in the LDA implementations (#3133)
I really was astonished that I was not aware of this page (although it is linked in LdaMulticore for benchmarking reasons).
