Merge branch 'modal-mergerequest-shorten-clipboard' into 'master'

edited stylesheet with mr modal fixes and added to changelog

## What does this MR do?
It shortens the modal command merge info elements.

## Are there points in the code the reviewer needs to double check?
I used the `.dark` class.. is that correct usage?
Made no issue as this is a minor upgrade to UI

## Why was this MR needed?
Clipboard buttons could obscure information in the merge info modal, this way its clean.

## Screenshots (if relevant)
