Fix registry cleanup script to use JSON output for reliable parsing (#5352)

The doctl --format output was being incorrectly parsed, causing the script
to read size values (18.67 MB) as dates. This resulted in all images being
deleted, including those with the 'latest' tag.

Switch to --output json with jq parsing for reliable field extraction.
