Fixed repo link in generated comment for cross repository dependency (#9863) (#9935)

* fixed link to issue in issue comments after adding/removing a dependency, before links assumed the issue was in the same repository. also changed the format of the displayed issue since the issue will not necessarily be in the same repo

* based on pr comments, changed to use HTMLURL instead of piecing together the issue url, and added an if statement around the issue link display as a nil protection

* only showing repo name in dependency comment if the issue is from another repo
