Update the challenge creation guide to use extensions

[escottalexander]

Currently the main branch repo contains instructions on how to add a challenge. It appears it is not giving advice on how to create an extension but instead, the prior challenge type.

We are going through these steps currently so we can submit a PR to change this if it seems helpful.

That would be amazing!

@carletex When you are able can you add a new branch called base-challenge-extension-template. I will a submit a PR to that branch with some files that should kick-start any new challenge extension. It should replace the need for the existing base-challenge-template branch. Feel free to name it whatever you think will work best.

Hey @escottalexander I added you on the repo, you should be able to create branches.

base-challenge-extension-template looks great to me!

Hey @escottalexander . As an option you can move old base-challenge-template branch to base-challenge-template--v0 as we do for all other challenges, and then recreate base-challenge-template for your needs so it will have clean git history.

Note: for some reason we didn't use template branch for challenges extensions, but we can fix it in future if needed

#278 and #279 will close this issue.

After thinking about it it seems the best way to get people set up will be for them to copy the files from the template onto the new extension they are creating after running yarn cli.

I renamed the existing template to base-challenge-template--v0 as suggested and have a PR into base-challenge-template.
