`Context` documentation improvement

[fritz-astronomer]

What do you see as an issue?

There are docs which suggest that Context is available and should be used - but the fields that are available are not mentioned in the doc definition of Context
https://airflow.apache.org/docs/task-sdk/stable/api.html#airflow.sdk.Context
Maybe it could link bidirectionally to/from
https://airflow.apache.org/docs/apache-airflow/stable/templates-ref.html
unless there's a better location for the fields that are available?

Are you willing to submit PR?

I can work on improving the documentation by clarifying the relationship between Context and the template context, and by adding clear cross-links between the Context API docs and the templates reference.
If that approach sounds reasonable, I’m happy to take this issue and adjust the solution based on feedback.
