Org-mode syntax highlighting
### Problem to solve
Syntax highlighting in markdown READMEs is indispensible. We should support this in org-mode
too.
### Intended users
* [Sasha (Software Developer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sasha-software-developer)
* [Dana (Data Analyst)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#dana-data-analyst)
* [Delaney (Development Team Lead)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#delaney-development-team-lead)
### Further details
Org-mode is a very popular format in the FOSS world, and is arguably more powerful than markdown.
Unlike markdown, it has a single, cohesive implementation that should be easy to adapt to.
### Proposal
Extract the language from `#+begin_src` blocks, and use the [rouge](https://rubygems.org/gems/rouge) ruby gem to highlight the code.
### Documentation
A url to org-mode docs should be enough, since org-mode is extensively documented. Or a side-note saying that `#+begin_src <lang>` blocks work the same as ``` blocks in markdown.
