#249 Introduced the ability to configure when a task should be acknowledged. We should update the documentation to reflect this.

[s3rius]

Let's convert this issue to general documentation update.

Because we have some other features that were not yet officially announced. Here's list of such topics to cover:

• [ ] Ack configuration docs;
• [x] Programmatic scheduling using new API;
• [x] New IPC approach (about to be published);
• [ ] Add more notes about available components;
• [ ] Add an entry about faststream, because we have a good integration with them.
