`coho update-release-notes` should also format PR/issue IDs as links

[janpio]

Currently:

$ for l in $ACTIVE; do (coho update-release-notes -r $l -g); done
Finding commits in cordova-plugin-splashscreen from tag 5.0.2 to tag master
Done formatting JIRA links for: E:\Projects\Cordova\coho Checkouts 2\cordova-plugin-splashscreen\RELEASENOTES.md

This creates something like:

* [CB-13826](https://issues.apache.org/jira/browse/CB-13826) Incremented plugin version.

But GitHub issues and PR IDs are not touched:

* CI: Use universal paramedic travis.yml (#210)

It would be nice if those were edited to

* CI: Use universal paramedic travis.yml ([#210](https://github.com/apache/cordova-plugin-splashscreen/pull/210))

Problem: The repo name is not available as a param, so we would have to probably 1) take it from the folder name, which could also be named "telephone", or 2) parse it from package.json.
