Use monospace fonts for GFM inputs

This is an MR for [this feedback suggestion](http://feedback.gitlab.com/forums/176466-general/suggestions/5593468-use-monospace-font-in-wiki-edit-content-textarea).

I'm not sure exactly where the best place for the fix is, but I opted for the typography.scss file.  Basically, all ``textarea.js-gfm-input`` elements are styled with ``font-family: $monospace_font;``.

*PS: this being my first MR to gitlab, I apologize if I missed any steps in the process; let me know what's missing and I'll correct it here & in future MRs*
