playbooks: Avoid using potentially broken DNF5

The Zuul executor got updated from Ansible 2.13.7 to 2.15.10, which now
has support for DNF5 [1] and the previous DNF5 Change [2] for Fedora 39
is now aiming at Fedora 41 (and Rawhide) [3].  Unfortunately, Ansible's
'dnf5' module is still under development and doesn't seem to match the
state of DNF5 in Fedora Rawhide, which causes:
  TASK [Install RPM packages]
  fedora-rawhide | ERROR
  fedora-rawhide | {
  fedora-rawhide |   "failures": [],
  fedora-rawhide |   "msg": "Could not import the libdnf5 python module
      using /usr/bin/python3 (3.12.3 (main, Apr 17 2024, 00:00:00) [GCC
      14.0.1 20240411 (Red Hat 14.0.1-0)]). Please install
      python3-libdnf5 package or ensure you have specified the correct
      ansible_python_interpreter. (attempted
      ['/usr/libexec/platform-python', '/usr/bin/python3',
      '/usr/bin/python2', '/usr/bin/python'])"
  fedora-rawhide | }

Trying to explicitly install python3-libdnf5, as suggested above, using
Ansible's 'command' module before using the 'package' module to install
the Toolbx dependencies, still ends up with:
  TASK [Install RPM packages]

  fedora-rawhide | AttributeError: 'Base' object has no attribute

Therefore, force the use of DNF4 when an Ansible job is being attempted
more than once [4].
