When using the post editor with a bundled theme active, there will be a number of `console.info` notices printed to the browser’s console.
These notices are caused by block patterns containing outdated and deprecated versions of `core/*` blocks. Before rendering the blocks, they need to be updated, and this process outputs information to the console.
Props ntsekouras.
