Congratulations on your first Pull Request and welcome to the Apache Airflow community! If you have any issues or are unsure about any anything please check our Contribution Guide (https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst)
Here are some useful points:

• Pay attention to the quality of your code (flake8, mypy and type annotations). Our pre-commits will help you with that.
• In case of a new feature add useful documentation (in docstrings or in docs/ directory). Adding a new operator? Check this short guide Consider adding an example DAG that shows how users should use it.
• Consider using Breeze environment for testing locally, it’s a heavy docker but it ships with a working Airflow and a lot of integrations.
• Be patient and persistent. It might take some time to get a review or get the final approval from Committers.
• Please follow ASF Code of Conduct for all communication including (but not limited to) comments on Pull Requests, Mailing list and Slack.
• Be sure to read the Airflow Coding style.
  Apache Airflow is a community-driven project and together we are making it better 🚀.
  In case of doubts contact the developers at:
  Mailing List: dev@airflow.apache.org

@KennyRich can you please rebase & resolve conflicts?
Also note that some of the S3 operators are also in contrib.
For example:

airflow/tests/deprecated_classes.py

Lines 1067 to 1068 in f4e04c7

	'airflow.providers.amazon.aws.operators.s3_list.S3ListOperator',
	'airflow.contrib.operators.s3_list_operator.S3ListOperator',

This means that contrib (which is deprecated) is now pointing to deprecated class. This is probably wrong and should direct to the new class directly(?)

@eladkal Thanks for the feedback, I'll do that and send in a PR

Please check with Breeze locally that test passes.
Currently if you will run:
pytest -s tests/core/test_core_to_contrib.py
It will fail. some imports are wrong and also you have some duplications (I didn't add comments on all issues... running the test will tell you what needs to be fixed)

[eladkal]

@KennyRich you are missing also fixes to test classes:
https://github.com/apache/airflow/tree/main/tests/providers/amazon/aws/operators
https://github.com/apache/airflow/tree/main/tests/providers/amazon/aws/sensors

Tests are still importing operators from old paths.
