Stop publishing sample docs

[onobc]

All sections in the samples doc are covered elsewhere and we should be able to stop publishing the docs.

Here is a list of each section in the doc along w/ its replacement

Java DSL

https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#_java_dsl REPLACED WITH https://dataflow.spring.io/docs/feature-guides/streams/java-dsl/#stream-java-dsl

Streaming

https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#_streaming WELL COVERED BY https://dataflow.spring.io/docs/concepts/streams/ https://dataflow.spring.io/docs/stream-developer-guides/ stream-applications

Task/Batch

https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#_task_batch WELL COVERED BY https://dataflow.spring.io/docs/concepts/batch-jobs/ https://dataflow.spring.io/docs/batch-developer-guides/

Stream/Launching Batch Job

https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#_stream_launching_batch_job WELL COVERED BY https://github.com/spring-cloud/spring-cloud-dataflow/tree/main/spring-cloud-dataflow-tasklauncher

Analytics Section

https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#_analytics REPLACED WITH https://github.com/spring-cloud/stream-applications/blob/main/applications/sink/analytics-sink/README.adoc

https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#_data_science REPLACED WITH https://github.com/spring-cloud/stream-applications/tree/main/applications/processor/semantic-segmentation-processor

Function Section

https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#_functions_in_spring_cloud_data_flow Based on old Spring Cloud Function Bridge https://github.com/spring-cloud-stream-app-starters/function/blob/main/spring-cloud-starter-stream-app-function/README.adoc which is supported OOTB w/ SCS now RECOMMEND USE stream-applications instead

Monitoring Section

https://docs.spring.io/spring-cloud-dataflow-samples/docs/current/reference/htmlsingle/#_monitoring REPLACED WITH https://dataflow.spring.io/docs/feature-guides/general/server-monitoring/ https://dataflow.spring.io/docs/feature-guides/streams/monitoring/ https://dataflow.spring.io/docs/feature-guides/batch/monitoring/
