What?

Add padding and margin support to the Comment Edit Link block.

Why?

To create consistency across blocks.

How?

Added the relevant block supports in block.json

Note that box-sizing: border-box was not applied to this block like in other implementations. Since the Comment Edit Link block is always contained within the Comments Template, box-sizing: border-box did not seem to be needed in my testing.

Testing Instructions

1. Insert a new Comment Edit Link block.
2. Confirm the Dimension control panel allows you to add both padding and margin.
3. Adding padding and margin.

Screenshots or screencast

The visualizers in the Site Editor are a little wonky, but not related to this PR.

theme.json, global styles and editing individual blocks work well.

This LGTM, too!

Yes, the sizing appears to be working nicely for me in the editor and on the site frontend without needing to add the box-sizing rule 👍

I'll merge this in and update the tracking issue.
