Fixing `msg` parameter for `debug` module (#4702)

According to [`debug` module documentation](https://docs.ansible.com/ansible/latest/modules/debug_module.html?highlight=msg), the correct parameter name is `msg`. With the previous `message` parameter name I was getting FAILED messages while ansible was trying to debug previous FAILED tasks.
