Update Pods Blocks to v3

[JoryHogeveen]

Description

Problem: https://wordpress.org/support/topic/wordpress-editor-background-grey-if-plugin-not-enabled/ Cause: https://wordpress.org/support/topic/editor-canvas-iframe-vs-div/

If all registered blocks are at API version 3, the canvas uses an iframe. If not, it uses a div.

Basically, our blocks need to be updated to the new v3 blocks to support an iFrame.
