## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

* The following paths are wrong 
* `airflow.providers.amazon.auth_manager.avp.entities` should be
`airflow.providers.amazon.aws.auth_manager.avp.entities`
* `["airflow", "datasets", "manager", "dataset_manager"]` should be
fixed as `airflow.assets.manager` but not
`airflow.assets.manager.asset_manager`
* `["airflow", "datasets.manager", "DatasetManager"]` should be `
["airflow", "datasets", "manager", "DatasetManager"]` instead

## Test Plan

<!-- How was it tested? -->

the test fixture is updated accordingly
