Fix unsecured Argo CD communications

Argo CD 3.5 introduces native mutual TLS (mTLS) support, enhancing the security of internal communications between its components by embedding encryption and identity verification directly into the application. This advancement addresses the limitations of one-way TLS and aligns with zero-trust architecture principles, ensuring that both client and server authenticate each other before data exchange, which significantly reduces security risks such as unauthorized access. Prior to this update, operators relied on complex external solutions like service meshes or custom scripts for encryption, which added operational overhead and maintenance challenges. The new mTLS feature simplifies this by enabling easy setup through a Kubernetes Secret, allowing for both shared and per-component certificate configurations, thus catering to various security needs and compliance requirements such as SOC 2, HIPAA, and PCI-DSS. The update facilitates smoother transitions from existing architectures and enhances traceability and security without the need for third-party dependencies, making it a valuable enhancement for diverse environments, from small-scale deployments to large, regulated enterprises.
