Need ability to set the Block api_version

[ggedde]

Currently the block api_version is at V3, but the default is still using V1.
See: https://developer.wordpress.org/block-editor/reference-guides/block-api/block-api-versions/

But it needs to be set when using register_block_type()

So we need a way to set it.
See this pull request which should resolve it: #1276

The pull request also adds a filter to set it globally:
Ex.

add_filter('carbon_fields_set_block_api_version', function () {
    return 3;
});

Thanks,
