Couchbase Cache support documentation still refers to previous version

Upgrade to Couchbase SDK v3

I think document should update about "Upgrade to Couchbase SDK v3".
It is very confused for new couchbase cache users.

CouchbaseCacheConfiguration

And I think CacheManagerCustomizers cannot working on couchbase cache. CacheManagerCustomizers cannot change about
CouchbaseCacheManager.

Thanks for the feedback. Are you saying that the documentation is out-of-date and does not work with v3 of the Couchbase SDK or that the migration to v3 of the SDK is confusing?

@scollector65 Andy and I chatted as I've review the PR and the cache documentation is indeed outdated, sorry about that. We will have to investigate how to offer a customization callback that offers the same feature as the current doc (I.e. prepareCache).

Let's tackle the lack of customization in #22573 as it is unrelated to the fact the doc is outdated. Thanks for the report @scollector65!

It turns out that the documentation had to be rewritten as part of fixing the customisation problem anyway.

This issue is now superseded by #22573
