Annotations: tweak annotations publish section

Removed 'Publishing individual annotation events' section separate from
'annotation publish', I think that's confusing. Just mentioned that you
can specify a data payload at the bottom of the publish section.

 To delete an annotation, use the `annotations.delete()` method on a channel. Pass in either a [message](/docs/messages) instance or the `serial` of the message to annotate. This method will publish an annotation message with an action of `annotation.delete`.

 It is also possible to subscribe to individual annotation events, rather than annotation summaries. These are the emitted when [publishing](#publish) or [deleting](#delete) an annotation.
 
 Individual events can be useful for activity feeds or detailed logging, however annotation summaries are generally more reliable and efficient for maintaining UI state.

-Publishing annotations is the [same as for summaries](#publish). The only difference is that you can additionally specify a `data` payload when publishing an annotation, which isn't included in an annotation summary.
