codeinsights-db: remove liveness/readiness probes (#1859)

These scripts do not exist in the base image (I based the YAML on codeinsights-db,
where it turns out bakes these scripts into the postgres image we ship.)

I will need to revisit adding these, for now removing so it does not produce broken
deployments.
