mypy-boto3-elb Type Stubs for AWS Elastic Load Balancing

mypy-boto3-elb provides type annotations for the `boto3` Elastic Load Balancing (ELB) service. It allows static type checkers like MyPy and Pyright to validate `boto3` calls, improving code quality and developer experience. The library version 1.42.3 matches the corresponding `boto3` version, and it's actively maintained with frequent updates reflecting changes in AWS services and `boto3` itself.
