Review Comment:
I am going through the operators we have in `amazon/aws` provider. In some
places we just have a type annotation saying it is a `str` value. While other
places have `str | None` with default `aws_default`. Do we want to continue
accepting `None` values and fallback to `boto3` looking for the credentials in
the `~/aws/credentials` file in general? In that case, should we update the
type annotation to `str | None` in all the operators? If we do not want to
fallback and want to mandate an Airflow connection to be used, should we raise
an exception when the `aws_conn_id` value is not set?
Additionally, I also see that some operators have `aws_conn_id` in their
`template_fields` but not all. Do we need to unify this experience across all
operators?
