### Tell us about your request Add a link to the return type to the fluent builder method in the docs. Currently docs like: https://docs.rs/aws-sdk-s3/latest/aws_sdk_s3/client/struct.Client.html#method.list_buckets don't link to the return type—customers need to click through to find the [send](https://docs.rs/aws-sdk-s3/latest/aws_sdk_s3/client/fluent_builders/struct.ListBuckets.html#method.send) method to figure out the actual return type. ### Tell us about the problem you're trying to solve.
