Modify for Amazon Linux 2023

[yuichisatake]

python3 is installed by default on amazon linux2023.
So, when I changed ansible's interpreter_python to "/usr/bin/python3" and executed the role, the following error occurred.

TASK [mackerelio.mackerel-agent : install mackerel-agent] ****************************************************************************************************
task path: /home/sysadmin/.ansible/roles/mackerelio.mackerel-agent/tasks/amazonlinux.yml:31
fatal: [10.16.4.68]: FAILED! => {"changed": false, "msg": "The Python 2 yum module is needed for this module. If you require Python 3 support use the `dnf` Ansible module instead."}`

I created a pull request that works with the pyton3 interpreter, so please consider merging it.

I see, yum module is strongly depends on Python 2.

We are trying to merge this PR onto main branch, however, I have some questions.

1. Could you add dnf support to files under tasks directory, such as amazonlinux.yml or main.yml?
2. If can't, are there technical issues?

@lufia
sorry. The location of the task file was incorrect.
We have corrected it, so please check it.
