I noticed that service is using a reference to hardcoded branch jdk-17 in the service-base-image repository which is outdated and using alpine-zulu v0.0.4 when other services don't have this branch hardcoded so are using main branch with alpine-zulu v0.0.5 by default

This MR is removing hardcoded reference to old branch so service can use latest base zulu image with latest security updates
