In brief you need to switch the registry from (iirc) docker.io/bitnami to docker.io/bitnamilegacy. Note that as of iirc tomorrow those images will no longer be updated. So the moment there is a high or critical cve you better have a plan to use a new image and likely helm chart or send broadcom cash. The old registry will continue to have a "latest" tag but this should not be used for production.
