Improve unapproved MR merge button message
Description
There is not a helpful "Merge not available" message when a merge request is pending approval. Right now it says a positive message "Ready to merged automatically", which is confusing because the merge button is greyed out.
Original slack discussion:
The MR still requires approval, but it says “Ready to be merged automatically.” That seems like a mistake but it’s my first time in this territory so maybe I’m missing something?
