fix display hook error message ## What does this MR do? Fix hook error message display. ## Are there points in the code the reviewer needs to double check? Probably Hook will return the plain multi line text. It is better `pre` tag than `h4`. I thought of another good looking display, but I did not come up with it. 😓 ## Why was this MR needed? When the hook returns an STDERR, "Merge in progress" button spinning forever. Due to javascript's error. ## Screenshots (if relevant) When update hook returns an error like ``` XXXXXXXX YYYYYYYY ZZZZZZZZ ```  ## What are the relevant issue numbers? Closes #24020 See merge request !7775 |
