Update ANSIBLE_CONFIG path for consistency in scripts

[floatingman]

Standardize the ANSIBLE_CONFIG path across multiple scripts to ensure consistency in configuration.

[Copilot]

Pull request overview

This PR standardizes the ANSIBLE_CONFIG environment variable path across multiple infrastructure automation scripts to use a centralized configuration file. Previously, scripts used different paths (such as ansible/rke2/default/ansible.cfg), but now all scripts consistently point to ansible/ansible.cfg at the root of the ansible directory in the qa-infra-automation repository.

Changes:

• Updated ANSIBLE_CONFIG path from feature-specific location to centralized ansible/ansible.cfg
• Applied changes consistently across shell scripts and Jenkins pipeline files
• Ensures all infrastructure automation uses the same Ansible configuration

Looks good! Could you run the elemental_harvester job and the pit.daily job pointing to this branch?
