refactor ♻️: Refactoring the tasks directory to include new roles and tasks.

The commit updates the `tasks` directory by adding new roles (`rapbian_desktop_prov.yml`, `test_remote.yml`, `update_roles.sh`) and tasks within these roles. This refactoring enhances the organization and maintainability of the Ansible playbook.
