This unpins us from the out-of-date v4.4.7 and instead installs the latest version from the "Boron" LTS release line. With this, we'll only have to spin up new instances to pick up security fixes, plus update the LTS release line again every year. (or three)
I haven't deployed this yet, but I did test the commands in a container, and the site's test suite runs fine on v6.9.1. (FWIW Travis CI has been testing on v6 for some time now)
