Got "Servname not supported for ai_socktype" when deploy Karapace Schema Registry

[shivam-cse]

I have experienced the same errors someone mentioned at : stackoverflow

Please take a look at the StackOverflow link in detail

I have used the latest container build image
image: ghcr.io/aiven-open/karapace
imageTag: 4.1.1

Note: I have GKE cluter where strimzi based kafka running in 'kafka' namespace, and try to deploy the karapace registry in 'karapace-shcema-registry' namespace
