Thanks for taking the time to submit this PR,

a couple of things:

• Please add a changelog fragment: https://docs.ansible.com/ansible/latest/community/development_process.html#changelogs-how-to
• Might be better to use scrub_none_parameters(): https://github.com/ansible-collections/amazon.aws/blob/main/plugins/module_utils/transformation.py#L110
• To help avoid regressions, please add an integration test which demonstrates the expected vs current behaviour: https://github.com/ansible-collections/amazon.aws/blob/main/tests/integration/targets/s3_object/tasks/main.yml
