Enable inline creation for Comments/Updates on task level

[#1]

The idea is to allow adding updates/comments to tasks through the inline edit functionality. 

We use a backlog project to manage multiple backlog tasks and need to add grooming notes to each of the tasks every week. We do this using the inline edit function on a task view. While we have been using a custom text field which enables us to edit line, it would be great if we could add a new update/comment using inline edit.

Ideally, we would be able to add updates/comments when we are inline edit mode. When saved the newly added update/comment would land in the updates section of the task. When not in edit mode the column should show the last update. 

Currently, there is no way to edit/add comments using inline edit on a task view.

@RowvillBh1 - agree that this would be nice to have! Two other existing solves in case you were not doing these....

1. Click on the task and open the right sidebar to add your updates,
   • Can add an update without leaving the backlog on the main portion of your screen
   • Can also see the recent update string from here
2. Add a faux updates paragraph custom field
   • This field can be updated inline
   • Does not automatically show in the "updates" string, but could be copied over through fusion
