Fix links in READMEs causing 404 errors in Github

In doc/contributing/README.md, doc/documentation/README.md, and
doc/development/README.md, there were links that referenced files in the
same doc directory but prepended the directory name. This lead to urls
that were broken due to having the directory name stated twice.
