Typo in document `Compnent`

Line 307 in fd0b7cf

The `@MessagingGateway` is meta-annotated with a `@MessageEndpoint` since version `6.0` and the `name()` attribute is, essentially, aliased to the `@Compnent.value()`.

docs page: https://docs.spring.io/spring-integration/reference/gateway.html

@Compnent.value() should be changed to @Component.value().
