Closing this as deprecated for the current Jira provider contract. This PR switches the provider toward a different jira CLI dialect (jira me, jira issue view --raw), while the current docs and provider setup are for go-jira (jira version, jira session, and the jira view command family). #442 is the smaller go-jira-compatible fix to keep reviewing.
