added priority field to issue description

If JIRA issue has a priority it will be displayed with other issue fields, since it's one of the most useful properties

This looks fine to merge. I'd just like to mention I'm looking for someone to take over this and other JIRA scripts if you are looking to contribute more 💖 Here are the open issues: https://github.com/github/hubot-scripts/issues?labels=jira&state=open

Thank, and what are the version policy for package.json? Since to get scripts updated automatically version has to change, so should I increase version with every pull request?

There's manual commands to run (ie npm publish), so I prefer not having the package.json updated in PRs. That way, I can bump the file, and git tag the release, and then npm publish, so we know there's a consistent sha between what's tagged and what's npm published.

I'll do a publish in the next day or so.

This is actually one reason I'd prefer more external packages, so they can be on completely different release lifecycles.
