Migrate Kafka Binder (& Streams) to Core Retry

[artembilan]

The Spring Retry project goes to its sunset;
therefore, a goal for the whole portfolio is
to get rid of its dependency while putting the project into a maintenance mode. Use Spring Core RetryTemplate API instead

• Fix @StreamRetryTemplate docs to talk about Core RetryTemplate. And fix respective tests to use a new import
• Migrate AbstractBinder to Core Retry
• Migrate DefaultPollableMessageSource to Core Retry and supporting retry API from Spring Integration
• Migrate KafkaMessageChannelBinder, including respective tests
• Fix typos in Javadocs
• Fix for some Spring Boot 4.0 breaking changes to make project to be built at least at some level
• Migrate Kafka Streams module to Core Retry
• Fix parent POM to not use -local repositories to avoid authentication
• Remove redundant repositories section from the Kafka binder as it is inherited from the parent
• Comment out spring-cloud-stream-integration-tests module since it fail with not related problems
• The Rabbit Binder would be fixed separately when Spring Boot is ready

While this is a breaking change internally, this does not affect the end-user API too much. Moreover, the rest of Spring projects are already doing such a breaking change migration. So, aim for spring-retry removal in the end anyway

The spring-cloud-stream-schema-registry-server fails for some Spring Boot incompatibility or my out-dated local SNAPSHOTs

@olegz I synced with @artembilan on this PR, and it looks good to me. I will let you merge the PR; however, before merging it, we need to re-enable the tests and investigate why the tests in the spring-cloud-stream-integration-test module are failing. We can separately investigate why the schema registry tests are failing, but that is not critical for this PR to be merged.
