RFR: 2397: Jira Issues with resoultion "delivered" should not be changed to "fixed"

[Zhao Song]

Currently, the Skara bot doesn't recognize "Delivered" as a valid resolution for resolved issues. As a result, when the bot finds an issue in a Resolved or Closed state with "Delivered" resolution, it will change the resolution to "Fixed." However, it shouldn't.

This patch is trying to make the bot recognize "Delivered" as a valid resolution for resolved issues, preventing unnecessary changes.
