Update Gradle dependencies to use implementation

[cppwfs]

Replace deprecated compile configuration with implementation across all Spring Integration reference 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.

Thanks.
I’m not sure how is that useful , but we should use relevant labels on issues or PRs.

compile is deprecated on older versions of gradle does not work on the latest gradle version. So why would we keep the syntax compile when the recommendation is to use implementation?

I’m not sure in your question.
I fully agreed with the change, so it has been merged.
What I meant is to add a documentation label to the PR since it is indeed about docs.
Just some issues management.

I see now. Thank you for the merge!
