Use replicaCount Value in Deployment Template

[epichb]

The configured replicaCount value was not used in the deployment config. This PR aims to remediate this issue.

i think a more appropriate way would be to remove the value from helm values and keep it hardcoded in the deployment.
factorio does not support running multiple instances at the same time.

I see your point. My original use case was scaling down the instance when nobody was on the server, but that is probably better done by scaling manually and (in my case) excluding replica count from the Argo sync.
