DURAL: Python3 Not Installed

[dfhawthorne]

Describe the bug
When re-installing the DURAL service, the playbook fails because Python3 is not installed.

To Reproduce
Steps to reproduce the behavior:

1. Run ansible-playbook -K create_test_server.yml
2. See error

Expected behavior
The playbook should complete without error.

Error Messages
The error messages are:

fatal: [dural.yaocm.id.au]: FAILED! => {"ansible_facts": {}, "changed": false, "failed_modules": {"ansible.legacy.setup": {"failed": true, "module_stderr": "Shared connection to dural.yaocm.id.au closed.\r\n", "module_stdout": "/bin/sh: /usr/bin/python3: No such file or directory\r\n", "msg": "The module failed to execute correctly, you probably need to set the interpreter.\nSee stdout/stderr for the exact error", "rc": 127}}, "msg": "The following modules failed to execute: ansible.legacy.setup\n"}

Additional context
N/A

A workaround to run the following command on DURAL:

sudo dnf -y install python3

This will probably be a documentation fix.
