modify revs_limit API docs

[torcolvin]

• Since allow_conflicts is no longer allowed, the default is just 50 for revs limit.

Example fixes, some much older. These are only the ones that were obvious to me:

• switch num_index_replicas to index.num_replicas
• remove allow_conflicts option
• remove enable_shared_bucket_access option
• switch server connection string from http:// to couchbase://

Pull Request Overview

This PR updates legacy and database configuration examples to reflect deprecated API changes, specifically removing the allow_conflicts parameter and updating related configurations. The primary change involves updating documentation for the revs_limit API to reflect that the default is now 50 rather than different values based on conflict allowance.

• Removes deprecated allow_conflicts and revs_limit configurations from example files
• Updates server connection strings from http:// to couchbase:// protocol
• Modernizes index configuration from num_index_replicas to index.num_replicas structure
