Highlight the `n Conflicts Remaining` label/button in the new merge editor

Type: <b>Feature Request</b> * The `n Conflicts Remaining ` is an extremely useful indicator to have when dealing with files that have multiple conflicts and are out of the lines of code that are viewable. * Failed to notice it the first few times I used the merge editor. * Opinion: I personally feel (and could be wrong) that the usability of this feature would increase or at least it would be more noticeable if it had some sort of icon/highlight/warn or error kind of indication.  Kudos to the VSCode team for the formidable Merge Editor.
