Fix bug 1473372: Make Docker setup default in developer docs (#998)

Make Developer Setup with Docker default and recommended way of
installing Pontoon locally. Rename it to Developer Setup and make it
the first item in the main menu. Rename the legacy Developer Setup to
Developer Setup with virtualenv.

Also included:
* Remove the NOTE 'Installation via Docker is still a fresh feature'
  and add a similar NOTE to legacy set up to use DOCKER.
* Update instructions for installing make on macOS.
* Change 'clone' operation to an actual step.
* Running tests section is already included in Contributing.
* Move Database and Building front-end resources sections under
  Contributing.
* Update .gitignore.
