Markaddonizio documentation 1

Updated documentation (readme) to match metadata, taking advice to have a bigger version jump.

Thanks @markaddonizio , looking forward to this release. 2 quick things:

1. Could the puppet version (in Metadata) be lifted to <9.0.0 so it declares compatibility with v8? Your tests should be raised to use the Puppet 7 & 8 versions to do so. Drop support for EOL Puppet v6 also.
2. I think the version update should be a major one, to v3.0.0. For example, the Vox release guidance suggests that dropping a Puppet version is a major version bump https://voxpupuli.org/docs/releasing_version/

Hey again @markaddonizio, I have created another PR that lifts the supported Puppet puppet versions to 7 & 8, and therefore with a major version bump.

I have updated the changelog. However the travis file needs updating IF it is used
