Add link to branch commits in "New coordinated pipeline" message
What does this MR do?
- Add a link to the commits list page of the auto deploy branch in the "New coordinated pipeline" Slack message. This would be helpful when we need to check for a cherry-picked commit.
Reduce the number of chars of the SHA that is displayed in the Slack message from 11 to 8, to match the number of chars displayed on the commit list page.
