refactor: use range for supported ansible versions

[gardar]

• Use version range for collection supported Ansible versions. Previous method for listing supported versions resulted in warnings on patch level versions.
• Adds CI script for properly parsing PEP440 version ranges.
• fixes: Warning message does not support Ansible version 2.14.6 #144

This won't work for ansible >2.15.0 (like the current 2.15.2), correct?

[ducnm0711]

The collection does not work with patch level version:

$ ansible --version
ansible [core 2.13.11]
  config file = /etc/ansible/ansible.cfg
  python version = 3.8.10 (default, May 26 2023, 14:05:08) [GCC 9.4.0]
  jinja version = 3.1.2
  libyaml = True

$ ansible-playbook commons.yml -t node_exporter
[WARNING]: Collection prometheus.prometheus does not support Ansible version 2.13.11

Any plans on merging this soon?

[SuperQ]

Nice. I suppose later we could add an option to skip some specific versions in testing that we don't want to care about.
