Issue description

Micronaut Data 4.2
Procedure invocations in repositories
Added possibility to have associations (JOINs) in DTOs>
Support for inserts, updates and deletes with RETURNING clause in repositories
MongoDB: Support arrayFilters
Kotlin: New coroutine variations of connection / transaction operations: io.micronaut.data.connection.kotlin.CoroutineConnectionOperations, io.micronaut.transaction.kotlin.CoroutineTransactionOperations
R2DBC: New connection status callback. Corrected cancellation.

---

Where should Procedure invocations in repositories link to so that user can learn more? https://micronaut-projects.github.io/micronaut-data/latest/guide/#hibernateProcedures or https://micronaut-projects.github.io/micronaut-data/latest/guide/#dbcProcedures. One section is in Micronaut Data data JPA and the other is in Micronaut Data JDBC.

---

We don't have any docs about this ? Added possibility to have associations (JOINs) in DTOs .

For:

MongoDB: Support arrayFilters

We don't have any example in the documentation. We should have documentation. But as a minimum can we at least link to the mongo docs: https://www.mongodb.com/docs/manual/reference/operator/update/positional-filtered/

---

For

R2DBC: New connection status callback.

Should we link to this javadoc? https://micronaut-projects.github.io/micronaut-data/latest/api/io/micronaut/data/connection/reactive/ReactiveConnectionSynchronization.html
