Per the scheduled release of spec 3.0 on June 2023, a major update to AsyncAPI docs is needed.

To this end, Jonas added a discussion point for Docs to upcoming Spec 3.0 community meetings. We'll use this time to help guide and support the community contributors who help us document these changes in docs in the weeks leading to the June release.

Overview of spec 3.0 release changes that require documentation in this task:

• Moving root properties tags and externalDocs to info feat: move root tags and externalDocs to the info object spec#794

⚠️ PLEASE NOTE:
Each of these tasks converted to issues does not imply a single PR; the community should expect to review multiple PRs PER task issue because each spec change introduces updates across all Docs content buckets. (i.e., The request/reply change introduces a need to create a Concepts doc, document further in upcoming new Spec 3.0 docs, and implies huge changes to current tutorials.)
