Documentation: update the introductory section

The second paragraph in the git(1) description section were meant to
guide people who are not ready to dive into this page away from here.

acquainted with Git was somewhat out of place.  Move the reference to
the "FURTHER DOCUMENTATION" section and push that section down.
