Reactions Block: add option to customize and / or remove the heading

[jeherve]

What

It would be nice if we could customize and / or remove the heading of the Reactions block.

On my site, I would like to be able to:

1. Use the heading level I want
2. Change the text
3. Customize the display of the heading (top border, style, ...)
4. Remove it entirely if necessary

Why

The more customizable the block is, the easier it will be for folks to integrate it on their sites.

How

Would it be possible to auto-insert a core group block instead, and that group block would have a heading block and a Reactions block? This way folks would then be able to customize it to their liking.

Agreed these would be nice! You should be able to edit the text, including an empty string that will remove it

If that can help, in Jetpack's Related Posts block we relied on InnerBlocks to allow a heading block before the actual related posts element:

Maybe we could do something similar with the Reactions block?
