Update Gradle dependencies to use implementation

Replace deprecated `compile` configuration with `implementation`
across all Spring Integration module documentation. The `compile`
configuration was deprecated in Gradle 4.0 and removed in Gradle 7.0.
This update ensures documentation examples use current Gradle best
practices.
