Clarify pipeline for merged results docs
What does this MR do?
I added a screenshot of what it should look like on an MR when pipeline for merged results succeeds. I also added a description of the commit that is linked to from the pipeline Widget on the MR.
Why?
I was just setting this up on a new project and my MR met both of the documented conditions for the pipeline for merge results not running:
- The target branch has changes that conflict with the changes in the source branch.
- The merge request is a Draft merge request.
It led me to think that it would be useful to include some information in the documentation that you can use to verify that a pipeline for merged results has run or to verify that the pipeline for Merged results did not run. This is clear if you remember what the UI looks like when a pipeline for merge results is successful but not so clear if you don't.
Verifying against the text of the MR widget is one way and verifying that the commit is an ephemeral commit that does not exist on the source or the target is another way to determine that the pipeline for merged results has indeed run.
I also think it's useful to document that the commit displayed is no longer the last commit for the source branch.
