[Internal]: Building block rule actions

[yctercero]

Description

The Detection Engine team was pinged about customer confusion on whether building block rules (BBRs) generate notifications. It seemed to me that by allowing users to add notifications for BBRs, it was understood as available functionality, but can also recognize the confusion. ChatGPT also thought notifications weren't configurable with BBRs 😄

I'm linking the docs - unsure of the most natural place to mention notifications.
