Add support for Rocky

[MikeCantCode]

There are some conditonals that filter out Rocky distributions. Here and here for example.

Adding Rocky to these conditionals would suffice.

- name: Manage crypto policies
  include_role:
    name: fedora.linux_system_roles.crypto_policies
  vars:
    crypto_policies_policy: "DEFAULT:AD-SUPPORT"
  when:
    - ad_integration_manage_crypto_policies | bool
    # Fedora and RHEL8+
    - (ansible_distribution == "Fedora" or
      (ansible_distribution in ['CentOS', 'RedHat', 'Rocky'] and
       ansible_distribution_version is version('8', '>=')))
