…hash exchange Adds reference for the new exchangeDeclareMode and queueDeclareMode metadata fields, and for the x-consistent-hash exchange kind. Also corrects the exchangeKind allowed values, which listed only fanout and topic although direct and headers have long been accepted.

The component validates exchangeKind against the same allowlist in both declare modes, matching the allowedValues in metadata.yaml. Signed-off-by: MyMirelHub <15373565+MyMirelHub@users.noreply.github.com>

Description
Documents the two RabbitMQ pub/sub features added in dapr/components-contrib#4552, and fixes an existing inaccuracy in the same page.
exchangeDeclareMode/queueDeclareMode— new section Use an externally managed topology, for brokers whose exchanges and queues are owned by the RabbitMQ Topology Operator, Terraform, or similar. Covers why the collision happens (PRECONDITION_FAILED), what each mode asserts, that dead-letter objects follow the same rule, and that queue arguments become the external owner's responsibility underqueueDeclareMode: passive.x-consistent-hash— new section Use a consistent hash exchange for partitioned ordering. The part worth being explicit about is thatroutingKeymeans the partition key when publishing and the queue's integer bucket weight when subscribing.exchangeKindallowed values — the table listed onlyfanoutandtopic.directandheadershave long been accepted by the component; this corrects the row and addsx-consistent-hash.Issue reference
Documents dapr/components-contrib#4553 and dapr/components-contrib#4554.
