Describe the solution you'd like
Localstack is used to simulate AWS services, like SQS queues. It would be great if we could have a module that help us to setup this container for the .NET version of Testcontainers.

Describe alternatives you've considered
When I needed to test againts a localstack container, I've spinned up it with the TestcontainersContainer class.

Additional context
The Java version of Testcontainers already have this module, I can help porting this code to C#. There's the #493 issue that aims to move modules to their own project, I think we could start this one here following the pattern.

In the initial implementation, the tests execute the script in the running container to create the sqs queue. The tests can be extended to cover the rest of localstack resources
