Include an observation and a link to PR templates at README.md

What article on docs.github.com is affected?

File README.md at github/docs

What part(s) of the article would you like to see updated?

After opening a multitude of PRs without realizing there was a template for it, I was warned about the situation. I hadn't found a link or a reference to a PR template when reading the README.md file, and I probably missed it right before the PR submission since I was rapid-firing PRs. IMHO adding a reference to PR templates (in the same manner that it's done to Issues templates) would be beneficial for other users.

Additional information

None at this time.
