I updated the examples for the latest recommended practices, ansible 2.9, and ansible-lint 6.x.  Links are updated as well.

I added a section for line wrapping - when ansible-lint complains about line length, what can I do other than "# noqa line-length"?  There are lots of recommended ways to do line wrapping.
