What this PR does / why we need it:
What this PR does - Adds an option to control the IPA replica count separately from the general .Values.replicaCount setting.

Why we need it:
When comparing xray-server-deployment and xray-ipa-deployment, it appears that a new key was introduced to manage server replica counts, but a similar option was not implemented for IPA replicas.
Current behavior:
xray-server-deployment:

• if not .Values.autoscalingServer.enabled
  replicas: {{ .Values.replicaCountServer }}
• end

xray-ipa-deployment:

• if not .Values.autoscalingIpa.enabled
  replicas: {{ .Values.replicaCount }}
• end

This update ensures consistent control over replica counts for both deployments.
