Alternate (simpler?) instructions on the README

[jpivarski]

Describe the bug

I tried to follow the example on the README:

cookiecutter-jupyter-book/README.md

Line 52 in 3977128

$ cookiecutter [email protected]:executablebooks/cookiecutter-jupyter-book.git

and had ssh troubles with github.com. I usually access it via HTTPS.

This worked, and I think it's simpler:

cookiecutter gh:executablebooks/cookiecutter-jupyter-book

Including too many options can be confusing for new users. Would the gh: option work for a larger set of users than the git@ ones? If so, then it can be the only instructions.

For comparison, https://github.com/scientific-python/cookie describes this method as well as one using copier instead of cookiecutter.
