Update README.md with removing outdated communication channels (ansible-collections#790)

Summary:
  As part of the consolidating Ansible discussion platforms and communication
  channels was decided to use the Ansible forum as the main place for questions
  and discussion.

  Reference: https://forum.ansible.com/t/proposal-consolidating-ansible-discussion-platforms/6812

  As part of this change, the IRC channel was removed by the PRs ansible-collections#778 and ansible-collections#774.

  However, the README.md file wasn't fully cleaned up from the outdated information.

  The `#ansible-kubernetes` channel on [libera.chat](https://libera.chat/) IRC isn't
  used by maintainers and contributors anymore.

  The Wiki page on the https://github.com/ansible/community/ was deprecated a long time ago
