Link to examples of high quality pull requests in the pull request template

For example, #278 does a great job of providing a complete usage example, and our PR template can guide others to do the same!

@mfisher87 Hey, do you have specific opinions on how we can approach this? I Think for solving this we need to have some PR'S that follow rules form PR template and we'll then just have to link to those PR'S.

The hard part is finding those PRs :) I don't know that we'll find one "perfect PR" that ticks all the boxes easily, but maybe we can find PRs that exemplify specific things from the list? For example, we have this checklist item:

• Populate a descriptive title. For example, instead of "Updated README.md", use a
  title such as "Add testing details to the contributor section of the README".

Instead of ... such as "Add testing details ..., we could find a PR with a clear and concise title and use that as the example, and continue to find other PRs that have stellar examples of the other qualities we're looking for. What do you think?

I will try to come up with a PR that follows the rubric. I think if we are able to encompass all the rules of the rubric in one single PR that would be great. I know it's the ideal case and it may not be plausible at this point in time but I think we should try!

That sounds great! Thanks for being willing to dive deep on this! ❤️

Can we use this PR as an ideal PR #763
