MINOR: Fix Streams DLQ config typo in upgrade guide (#21551)
### Problem
The Kafka Streams 4.2 upgrade guide documents the DLQ configuration as:
`errors.deadletterqueue.topic.name`
However the StreamsConfig constant defines the property as:
`errors.dead.letter.queue.topic.name`
This mismatch may lead users to configure the wrong property.
### Solution
Update the upgrade guide to use the correct configuration key.
### Scope
Documentation-only change. No functional impact.

### Other changes
-Kafka Streams now supports Dead Letter Queue (DLQ). A new config
`errors.deadletterqueue.topic.name` allows to specify the name of the DLQ
topic. When set and `DefaultProductionExceptionHandler` is used, records that
cause exceptions will be forwarded to the DLQ topic. If a custom exception
handler is used, it is up to the custom handler to build DLQ records to send,
hence, depending on the implementation, the `errors.deadletterqueue.topic.name`
configuration may be ignored. `org.apache. [...]

We introduce a new `org.apache.kafka.streams.CloseOptions` class which
replaces the existing `org.apache.kafka.streams.KafkaStreams$CloseOptions`. The
latter is deprecated and will be removed in the next major release.
`CloseOptions` class allows to specify close timeout and group membership
operation - whether the consumer needs to leave the group or remain in the
group. More details can be found in
[KIP-1153](https://cwiki.apache.org/confluence/x/QAq9F).
