Mark Paluch 393a81d4a9 Omit cancellation of transactional Monos in TransactionOperator
TransactionOperator.as(Mono) now no longer short-cuts via a Flux.next() but provides an implementation via Mono.usingWhen(…).
The short-cut previously issued a cancellation signal to the transactional Mono causing the transaction cleanup to happen without a handle for synchronization.

Using Mono.usingWhen(…) initiates transaction cleanup when the Mono completes eliminating the need for cancellation of the transactional Publisher.

This change does not fully fix gh-23304 but it softens its impact because TransactionalOperator.transactional(Mono) avoids cancellation.
