Error in local install instructions

[jaraco]

I ran the local install instructions on a macOS 10.13 system with Ruby installed via Homebrew, but got the following error when trying to run the server:

python3statement.github.io feature/cherrypy $ jekyll serve -w
Traceback (most recent call last):

Seems the recommendation by the error message does work around the issue:

python3statement.github.io feature/cherrypy $ bundle exec jekyll serve -w

Here's the full install log.

Yeah I always use bundle with jekyll, I think we can update the instruction.
It is also pre-deployed on netlify so we could actually tell people: send a PR, and click on the preview link if you can't get it to work on your machine.

See #152, I'm not a ruby person, so invocationas are magics to me.
