Update GhprbTrigger.java

Just spent some time tracking down the cause of this issue which started appearing after someone had disabled the GitHub plugin. The wording change will make the cause of this issue clearer to the user to allow for a quicker resolution.
"ghprbPullLink" - Added capturing the link to original Pull-Request so that the Jenkins Job can "link-back" to the Pull-Request on GitHub that actually triggered the Job in the first place

"ghprbSourceBranch" - Added capturing "source-branch" name in a Pull-Request (since it would contains information like Ticket Number which is essential for integration with Tracking Systems (like JIRA, RALLY, BUGZILLA etc…)

Sample Source-Branch name "Bug1234-nirav-fix-issue-abcd" this allows to update the ticket with ID-Bug1234 stating that a PR was opened for this ticket
