S3 get_bucket_location Would Benefit from Deprecation Attribute

### Describe the feature

The AWS [S3 API documentation](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketLocation.html) notes that HEAD should be used instead of get_bucket_location, presumably because of the non-standard return values for us-east-1/eu-west-1.

Currently, the rust SDK doesn't include a [deprecated attribute](https://doc.rust-lang.org/reference/attributes/diagnostics.html#the-deprecated-attribute), which makes it easy for developers to use a function call that is easy to misuse.

### Use Case

Deprecation attributes on get_bucket_location would help developers avoid using a method that is easy to misuse (in favor of the recommended HEAD method).

Start by locating the Rust SDK entry point for the S3 get_bucket_location operation and compare it with the recommended HEAD operation. Add the Rust deprecation attribute to get_bucket_location, preserving the guidance that HEAD should be used instead, and verify that the SDK emits the expected deprecation warning.
