Update apiVersion of all blocks to version 3

[fabiankaegy]

ElasticPress contains several blocks. These blocks currently all use apiVerson: 2. In order to not prevent adoption of the iFramed post editor these should get updated to apiVersion: 3.

Version 3 (>= WordPress 6.3)
The post editor will be iframed if all registered blocks have a Block API version 3 or higher and the editor has no classic meta boxes below the blocks. Adding version 3 support means that the block should work inside an iframe, though the block may still be rendered outside the iframe if not all blocks support version 3.
