Enhancement: Add Discord message to GitHub Issue

[JacobCoffee]

Summary

We currently have the "Create a GitHub Issue" app, but it would be nice to be able to select a single message and send it into an issue.

Basic Example

• Add new app option for adding the message
• On click, modal popup to input the issue number.
• Prefill with the default configured repository, but allow changing to another one inside of the same organization.
