Restore internal transaction insert/replace methods used by Spring Data Couchbase

Suggested Release Note

This release improves compatibility with Spring Data Couchbase by reversing an internal API change present in Couchbase Java SDK 3.6.2 and 3.7.0 that prevented upgrading to the latest Couchbase SDK independently of the Spring Data Couchbase version.

When support for binary transactions was added to core-io 2.6.2 (Java SDK 3.6.2) for JCBC-2135, the method signatures of some internal methods changed. These methods are called by Spring Data Couchbase's transactions implementation. This prevents Spring Data Couchbase users from upgrading to a more recent version of the Java SDK.

To fix the issue, we'll restore the original method signatures.
