I've confirmed that this closes #723, both with tests & with running example 02 while setting overwrite_input to False.

@tcompa I will already merge now so we can proceed with the release & deployment on Monday. The main thing where a review would be great is the new _copy_tables_from_zarr_url function. I already opened an issue here so we can review this further: #725
