`transform` and `through` are removed in 4.0. Since users cannot
reference them in 4.0 document, it's not good to keep using them as
example in `repartition` description.

Pull request to implement KIP-1111, aims to add a configuration that
prevents a Kafka Streams application from starting if any of its
internal topics have auto-generated names, thereby enforcing explicit
naming for all internal topics and enhancing the stability of the
application’s topology.
- Repartition Topics:
All repartition topics are created in the
KStreamImpl.createRepartitionedSource(...) static method. This method
either receives a name explicitly provided by the user or null and then
builds the final repartition topic name.
- Changelog Topics and State Store Names:
There are several scenarios where these are created:
In the MaterializedInternal constructor.
During KStream/KStream joins.
During KStream/KTable joins with grace periods.
With key-value buffers are used in suppressions.

Most of the changes are obvious clean-ups/fixes. A couple of noteworthy items:
1. Support for non LTS versions is clarified (we were incorrectly stating full support
for Java 23).
2. TLS version negotiation details are clarified.

There is an overlap between two sections in the current version of streams-config.html as described in KAFKA-14404.
The goal of this fix is to remove the overlap as well as describing some other parameters and their default values

Relax non-null FK left-join requirement.
Testing Strategy: Inject extractor which returns null on first or second element.
Reviewers: Walker Carlson <wcarlson@apace.org>
[KIP-962](https://cwiki.apache.org/confluence/display/KAFKA/KIP-962%3A+Relax+non-null+key+requirement+in+Kafka+Streams)
The key requirments got relaxed for the followinger streams dsl operator:
left join Kstream-Kstream: no longer drop left records with null-key and call ValueJoiner with 'null' for right value.
outer join Kstream-Kstream: no longer drop left/right records with null-key and call ValueJoiner with 'null' for right/left value.
left-foreign-key join Ktable-Ktable: no longer drop left records with null-foreign-key returned by the ForeignKeyExtractor and call ValueJoiner with 'null' for right value.
left join KStream-Ktable: no longer drop left records with null-key and call ValueJoiner with 'null' for right value.
left join KStream-GlobalTable: no longer drop records when KeyValueMapper returns 'null' and call ValueJoiner with 'null' for right value.

KIP-914 introduced a new boolean isLatest into Change to indicate whether a change update represents the latest for the key. Even though Change is serialized into the table repartition topic, the new boolean does not need to be serialized in, because the table repartition map processor performs an optimization to drop records for which isLatest = false. If not for this optimization, the downstream table aggregate would have to drop such records instead, and isLatest would need to be serialized into the repartition topic.
In light of the possibility that isLatest may need to be serialized into the repartition topic in the future, e.g., if other downstream processors are added which need to distinguish between records for which isLatest = true vs isLatest = false, this PR reserves repartition topic formats which include isLatest. Reserving these formats now comes at no additional cost to users since a rolling bounce is already required for the upcoming release due to KIP-904. If we don't reserve them now and instead have to add them later, then another bounce would be required at that time. Reserving formats is cheap, so we choose to do it now.
