copilot-bluespec: Adjust issue numbers in changelog. Refs #623.

The `copilot-bluespec` package was originally developed in an external repo
(https://github.com/Copilot-Language/copilot-bluespec), but there is interest
in having all Copilot projects and libraries merged into the main
https://github.com/Copilot-Language/copilot repo for ease of management.

Now that the `copilot-bluespec` package lives in the `copilot` repo, this
adjusts the issue numbers in the `copilot-bluespec` changelog to refer to the
old repo so that they will not be confused with issues in the `copilot` repo.
