README: Add Communication section with Forum information (#514)

SUMMARY
Dear maintainers,
As a part of the Consolidating Ansible discussion platforms initiative, this PR adds the communication section template defined by the community to the README. Similar PRs are being raised across all included collections under the ansible-collection org for now.
If you have other tags/forum groups related to the collection I didn't spot, please update corresponding lines by suggesting changes to the PR.
IMPORTANT: please, consider moving your WG mentioned in README to the forum group, request it using https://docs.ansible.com/ansible/devel/community/communication.html#requesting-a-forum-group and update the README (or let me know)
