Docs: Explicitly mention new behavior coming in WP 6.6 for block variations

[gziolo]

What?

Adds mentions about the behavior change coming in WP 6.6 for Block Variations.

Why?

WordPress 6.6 is still not released, so it will be helpful to clarify the differences between WP major versions.

How?

Updates to the documentation.

Code styling changes come from the Prettier integration, which I have always enabled in my IDE.

I added the "Backport to WP Beta/RC" label since I think we'd like these changes in 6.6, as that's what determines what will be at https://developer.wordpress.org/ IIUC.

Historically, we have always been using trunk to generate developer docs for the block editor. So, we can verify that in 15-20 minutes. Link:

The changes are already synced in the block editor handbook. Removed the label.
