Hi, I noticed that when setting the number of replicas to 0 or "0" the variable gets interpret as a boolean and the template does not render the replicas field in the deployment yaml

Hi @pathakhimanshucs,

I set the replicas to "0," and everything works even without my PR.

In the PR, I removed the condition for how the replicas are populated.
