Add Dashboard Support #72: CI && Pack bump

The latest versions of the `jira` library require `python >= 3.8`. In
light of the fact that `StackStorm` is going to shed support for
`python3.6` (which is EOL
https://www.python.org/downloads/release/python-360/) this pack is
updating to stop testing `3.6` and bumping the pack to the next major
version to signal a potentially breaking change.
