The --registry-mirror we use isn't that stable and it would be better to use specific image names instead. We probably need to add something like this to testcontainers.properties:
ryuk.container.image = harbor-repo.vmware.com/dockerhub-proxy-cache/testcontainers/ryuk:0.4.0
And also use something like https://github.com/spring-projects/spring-data-jpa/blob/699d3a2e57e39dc50df67337dfe696de93a3dd4a/spring-data-jpa/src/test/java/org/springframework/data/jpa/support/ProxyImageNameSubstitutor.java

We might also want to update CI to somehow ban hub.docker.io so we know that we've caught everything.

We can get rid of this after all releases are done from GitHub actions.
