Remove mention of github-markup in Wiki clone help
We drop the mention of gem install github-markup
for the following
reasons:
- Most of our custom markup logic is bundled in the GitLab Banzai rendering.
- github-markup is no longer maintained, and we actually use our own fork: gitlab-markup.
- Installing gollum automatically installs Kramdown and github-markup.
