URL: https://github.com/apache/airflow/issues/45854
### Apache Airflow version
2.10.4

### What happened?
The pull request added a new feature to the Apache Airflow project to better
support lists in the setup and teardown context manager: a subclass called
context_wrapper was created to enable the use of lists on the right-hand side
of the context manager, resolving a problem where lists could not be used
directly, improving the context manager's functionality and usability. The
implementation included two commits that improved typing and made sure lists
were handled correctly, which in turn allowed for more flexible task management
in the Airflow framework.
### What you think should happen instead?
Instead of the prior limits where lists could not be utilised effectively
within the setup and teardown context manager, the implementation of the
context_wrapper should allow seamless integration of lists in the context
manager. This modification should enable users to simply manage many jobs as a
list, boosting the overall functionality and flexibility of task execution.
Previously, users were unable to quickly organise and complete various
activities due to the inability to use lists directly on the context manager's
right-hand side. The context manager's usability was restricted by the lack of
this capability, which would have resulted in more complicated and
difficult-to-read code when handling task groups. These problems will be fixed
and a more user-friendly experience will be offered by the new implementation.
### How to reproduce
To reproduce the problem, take these steps:
Set up the environment: Make sure you are using the correct version of the
software, which includes the context manager, and that you have all the
dependencies you need.
Make an example script: Create a script that tries to use the context
manager's right-hand list for setup and takedown operations. For instance:
Python
Using context_manager(tasks), copy and edit tasks = [task1, task2, task3]:
# Execute tasks
Run the script: Execute the script and look for any unexpected behaviour or
problems pertaining to the context manager's use of the list.
Check for limitations: Make a note of any problems or error messages that
come up using this method, which would suggest that the context manager is not
supporting lists as it should.
