This commit refactors task names across multiple files to improve clarity and maintain consistency, ensuring that each task name accurately reflects its purpose and using the latest `ansible.builtin` modules where applicable.
This refactoring includes updating the README, changing the role name to focus on Proxmox VE, enhancing compatibility matrix, and refactoring default values for role variables. Handlers are updated to manage apt cache, restart pveproxy, and reload systemd. Role metadata is also updated for better Proxmox VE provisioning.
