Correct indentation for k3s_upgrade command

[dbanetto]

I recently updated my usage of k3s-asible to the latest from master and ran ansible-playbook -i ./inventory.yml ./playbooks/upgrade.yml which was getting me the following error

TASK [k3s_upgrade : Install new K3s Version] *****************************************************************
   fatal: [nuc]: FAILED! => {"changed": true, "msg": "Unsupported parameters for (ansible.legacy.command) module:
    environment. Supported parameters include: _raw_params, _uses_shell, argv, chdir, creates, executable, expand
   _argument_vars, removes, stdin, stdin_add_newline, strip_empty_ends."}

After a while I noticed that the changes from cd543a6 was not correctly indented for roles/k3s_upgrade.

I've managed to get my branch working this patch & running 1.33.4+k3s 🎉
