fix: Update role with ansible-lint recommendation

[Heniland]

This change includes a few minor changes.

• Use ansible FQCN names over short names
• Added become: true on specific modules that required privilege. (Make it clear which module needs privilege escalation.)
• Add Nouveau driver module to blacklist on Ubuntu when installed without Cuda repo
• for modprobe i used community.general.modprobe as it is recommended by Ansible Lint (You should use canonical module name community.general.modprobe instead of ansible.builtin.modprobe. )
