Merge branch 'gemfile_fix' into 'master'

Add explicit reference to rouge 1.10.1

We are relying on rouge 1.10.1 but nothing is referencing to this version and it is easy to lose this dependence. Previously, it was updated directly in Gemfile.lock which is not reliable way :)

https://gitlab.com/gitlab-org/gitlab-ce/commit/e20529cec4f6de0c2c1589da99abb8714ea1c1c1

`gollum-lib` has a dependence `rouge 1.9` which is old for us.
