Enhance documentation for retrieving `triggering_asset_event` from `Context`, using Jinja, etc.

[jroachgolf84]

Description

Provide enhanced documentation for the different ways that Airflow users can retrieve information about a Triggering Asset Event (triggering_asset_event) from Context, using Jinja, etc.

Currently, the docs shown here (https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/asset-scheduling.html#fetching-information-from-a-triggering-asset-event) don't provide enough information for users to confidently get started.

Use case/motivation

Asset-driven scheduling is one of the flagship features of Airflow 3.0, and proper documentation helps users get started quicker!
