[MOSIP-44390] Fix deprecated Ansible configurations

[bhumi46]

• Replace ANSIBLE_STDOUT_CALLBACK=yaml with default callback and ANSIBLE_CALLBACK_RESULT_FORMAT=yaml
• Replace ANSIBLE_CALLBACK_WHITELIST with ANSIBLE_CALLBACKS_ENABLED
• Replace ANSIBLE_COLLECTIONS_PATH with ANSIBLE_COLLECTIONS_PATHS

This resolves RKE2 installation failures due to removed community.general.yaml plugin in version 12.0.0

Summary by CodeRabbit

• Chores
  • Updated Ansible environment variable configuration to ensure proper collections path resolution.
  • Refined Ansible callback settings to improve output formatting and task profiling during cluster deployments.

Walkthrough

Two Ansible configuration shell scripts updated with revised environment variable names and settings. ANSIBLE_COLLECTIONS_PATH renamed to ANSIBLE_COLLECTIONS_PATHS in the PostgreSQL setup, and callback configuration restructured in the RKE2 cluster Ansible runner with stdout callback and result format adjustments.

Changes

Cohort / File(s)	Summary
PostgreSQL Setup terraform/modules/aws/postgresql-setup/postgresql-setup.sh	Renamed environment variable ANSIBLE_COLLECTIONS_PATH to ANSIBLE_COLLECTIONS_PATHS for Ansible collections path configuration.
