This commit replaces a big chunk of the instructions relative to the
environment setup with a reference to the equivalent steps listed in the
contribution guide. It also moves the content of the "Create your first
PR" section from chapter 16 to chapter 2, as readers were struggling
with the Git configuration required to push their work to GitHub as they
progressed through the tutorial.
