fix: update Ansible inventory to use dynamic SSH key paths

- Modified update_ansible_inventory() method to dynamically replace SSH key paths
- Fixed SSH connectivity issues in GitHub Actions by using temporary key locations
- Added regex pattern matching for both IP addresses and SSH private key file paths
- Ensures Ansible uses correct temporary SSH key instead of hardcoded ~/.ssh/testing_rsa

Resolves SSH 'no such identity' errors in CI environment.
