License pages linked to from onboarding page should have license text

[C-Saunders]

The MIT and CC-BY-SA-4.0 pages do not have the license text on them right now.

I think, based on this part of the website code, that the pages_controller is looking for these in the "pages" directory of this repo, but the license markdown files are in the "licenses" folder instead.

I am happy to make a PR to move those files into the "pages" directory, but I wasn't sure if it would be better to adjust things on the website side instead.

Thanks. Yeah - this seems to be a bug! We'll fix it in website. Thanks.
