Remove button hover CSS from theme.json when WordPress 7.0 is released

[hchouhan]

Summary

Remove button hover CSS workarounds from theme.json once WordPress 7.0 is released (April 9, 2026). The :hover property will be properly supported in block variations.

Background

Currently, button hover styles are implemented using the css property in theme.json because the :hover property is not supported in block variations. This will be fixed in WordPress 7.0.
