fix linting

[tomByrer]

To add it to the 'awesome' master list, seems that the formatting here doesn't conform to their liking:

sindresorhus/awesome#2442

Pull request put in for footnotes section. They need a different heading (sindresorhus/awesome#2442 (comment)) however, which may be a little trickier. @ringabout How should we approach it? Maybe keep the crown part of the image and append "Awesome Nim" in markdown?
