Support for S3 dual-stack endpoints

[a10y]

Describe the bug

S3 supports both standard endpoints, e.g. s3.REGION.amazonaws.com, as well as a dual-stack endpoint variant, which allows clients to resolve either IPv4/v6, e.g. s3.dualstack.REGION.amazonaws.com

To Reproduce

The following unit test using the DefaultObjectStoreRegistry fails to properly resolve a store for a dualstack endpoint:

    #[test]
    fn test_resolve_s3_dualstack_endpoint() {
        let registry = DefaultObjectStoreRegistry::new();

        let url = Url::parse(
            "https://s3.dualstack.us-east-1.amazonaws.com/static.customizedgirl.com/images/design/3747d20127af39238a380d4fface92b1_1639568_0_bigger.jpg",
        )
        .unwrap();

        let (_store, path) = registry
            .resolve(&url)
            .expect("registry should resolve S3 dual-stack endpoints");

        // The bucket (`static.customizedgirl.com`) is the first path segment and
        // should be stripped, leaving the object key as the trailing path.
        assert_eq!(
            path.as_ref(),
            "images/design/3747d20127af39238a380d4fface92b1_1639568_0_bigger.jpg"
        );
    }

Expected behavior

The registry should return an AmazonS3 store with the dualstack endpoint configured and the us-east-1 region set.

Additional context

I noticed this while trying to write some code that downloads data from the PIXMO dataset on HuggingFace, which is a collection of image URLs and descriptions.

The repro above uses the URL which failed for me.
