SUMMARY
Hello. 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 your forum group and/or tags related to the collection, please update corresponding lines by suggesting changes to the PR.
If the collection is not present on the Ansible forum yet, please check out the existing tags and groups - use what suits your collection. If there is no appropritate tag and group yet, please request one. Then update corresponding lines by suggesting changes to the PR.
Presence in the forum will soon likely become a part of the Collection inclusion requirements.
