Artful to Bionic

The Ubuntu Artful builds do not install on Bionic so removed "(and Newer)" from the link text.

Changed stable_ubuntu_max_supported_version to Bionic as it is supported by the ppa.

It does claim all Ubuntu versions from Trusty right through to (now) Bionic are on the ppa as version 2.1.1 but this is not in fact correct. Maybe close enough to accurate to leave as is though??....
