* Fix typos and language in README
* Fix new line in the end of `application.yml`
* Move `@Bean` for `RabbitMQContainer` as a regular `static` property on the class with a `@Container`
* Use `@Testcontainers(disabledWithoutDocker = true)`
* Move `@RabbitListener` method directly to test class
* In the end we don't need extra `@TestConfiguration` class at all
