Fix links to pages within the wiki for RDoc and AsciiDoc formats
gitlab-ce#18019 fixes wiki linking for markdown pages.
RDoc and AsciiDoc links are broken as well, and should probably be fixed.
Expected Behavior
- Wiki linking should be consistent with the documentation in '/help/markdown/wiki.md`
- The documentation is currently in gitlab-ce!4372
