Good First Issues

• new feature: Allow s3 service to configure assume role's duration-seconds #4976: Allow S3 service to configure assume role's duration-seconds. This involves adding support for configuring the duration of assume role sessions. A good entry point for contributors interested in AWS services.
• new feature: Allow s3 service to configure assume role's tags #4975: Allow S3 service to configure assume role's tags. This issue requires adding support for setting tags in assume role configurations, making it a straightforward task for new contributors.
• Implement Write Returns Metadata for all services #5693: Implement Write Returns Metadata for all services. Contributors can extend this feature for specific services by extracting metadata from write responses.
• Tracking issues of RFC: Object Versioning #2611: Tracking issues for Object Versioning. Tasks include making the version field effective in services like azblob, gcs, and gdrive. A great opportunity to learn about versioning in object storage.
