Allow @mention in My Updates Comment Field

[#1]

Description - I would like users to be able to @mention someone when they make a comment in the Approve, Changes, or Reject comment boxes.

Why is this feature important to you - This would ensure the comments from the user are seen right away and by the correct person/people.

How would you like the feature to work - When typing in the Comments boxes from the Approve, Changes, or Reject section, someone would include an @mention to a person or team and that message would generate an email update to the person/team @mentioned.  The update would be connected to the document (like it is when a Comment is made in the Document Summary Updates section along with showing the decision made.

Current Behaviour - Users have to navigate to the main Updates page to make comments which requires multiple extra clicks around the Project.
