Provide link to the PEPs GH pages on readme.

The PEPs rendered in GitHub Pages look really neat. Thanks @AA-Turner for working on it!

It would be great if we could include the link to the GitHub Pages version of the PEP on the readme.
Perhaps it would be obvious for some folks, but it took me awhile to find it: https://python.github.io/peps/

Thanks :)

Can add to PR #2016 that's already updating the readme file, I guess my concern would be advertising it too much until some sort of end state is worked out -- Brett originally mentioned in #3 to set up peps.python.org, but I imagine that will take a while (of course I'm committed to being involved to see things through).

If that isn't an issue for you will add it to the README, just wanted to check first.

P.S. haven't forgotten about setting up the test RtD environment, had intended to do it today but ended up with no spare time at the end of the day, and writing a few paragraphs for a readme is a lot easier! It might be the weekend though that I manage to find time. Sorry.

I think we can add a note on the readme mentioning that the GH pages version is yet not "official" and still in preview/development stage.

fab, will add
