Remove the "kb/api-version-3/" prefix from relative links

[RyanLB]

Fixes #55. Removes the "kb/api-version-3" prefix from relative links any time it appears.

@et this looks good to me. Can we merge?

i like #YOLO

@humeansacrifice says she was having problems with these links locally...we should revert this unless someone can confirm this works properly

[bmsteele]

@et yep reverted for now. When you test locally, the change is good if you manually append a trailing slash (so locally kb/api-version-3/object-field-references doesn't work but kb/api-version-3/object-field-references/ does —— but this should be handled nicely with a 301 redirect on our web server anyway).

All that being said... I'm missing something here. Not sure why these links stopped working in the first place. I had a dated local copy and didn't really see any differences.

I actually just tried this locally and it seemed to work fine. Super good fix to handle those busted links. @humeansacrifice can you provide some details as to what your issue was?

[humeansacrifice]

@et I get 404s for the links that were previously broken.

Thanks @RyanLB! I believe we had some people on different versions of mkdocs but those are fixed.
Your changes are now live.
Much ❤️
