Comment Date: Add spacing support

• Tracking: Addressing Design Tooling Consistency #43241
• Tracking: Dimensions Design Tools Consistency #43243

What?

Add padding and margin support to the Comment Date 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 Date 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 Comments Date block.
2. Confirm the Dimension control panel allows you to add both padding and margin.
3. Adding padding and margin.

Thanks for the ping @ndiego! I'm travelling at the moment, but should be able to take a look through these PRs sometime next week / over the next few days if no-one beats me to it. What do you think about adding in a stylesheet and box-sizing: border-box rule for these ones, too? In principle, I suspect any block that has a wp-block-$name classname attached to its wrapper element, and that wrapper element is a div (or block-level element, which is probably all of them), then it'll likely need the rule to be added (and a corresponding stylesheet if one does not already exist).

Thanks so much again for helping get all these opt-in PRs up!!

This LGTM, too!

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

Apologies for going quickly earlier and not reading this comment! Yes, this appears to work nicely without needing to add the border-box rule 👍

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