Modify kedro-airflow plugin to support namespace-based DAG grouping

[DimedS]

Description

Use the helper functions implemented in Kedro as part of #4376 to modify the kedro-airflow plugin. This modification will enable users to convert their Kedro pipelines into Airflow DAGs grouped by namespaces.

For the parent discussion, see #4319.

Will this remove the functionality to group by tags which is currently in this plugin?

Currently, there is no functionality to group by tags in kedro-airflow. The only existing grouping feature is group_by_memory. For the purposes of this PR, we will leave it as it is. However, as a potential next step (if this approach proves successful), it would make sense to implement group_by_memory in Kedro to enable similar functionality across other plugins.

As of now, we have agreed not to include grouping by tags in deployment functionality.
