During signup: values page mentioned but not linked to

The signup process recommends we familiarize ourselves with "our Values." However, at the time, I couldn't find them easily by browsing.

Eventually I found the ["Exercism's Values"](https://github.com/exercism/website-copy/blob/057e560dc3ebfe3a2ad782eed92e3843023de61d/pages/values.md) page using a GitHub search. Perhaps we, while signing up, should be able to read this if we wish?

Most places that mention our Values should, I suppose, also include a link to them—for example, in the Terms of Service and the Privacy Policy. During the signup process, I didn't easily see such a link—at least that was my experience.

This idea may have been considered before. Perhaps it was rejected in order to minimize the amount of reading required (and offered) during registration.

Would a pull request on this be welcome?
