This pull request improves the OpenSearch indexing process for the search_sync_worker service. It adds a function to trim long strings to avoid indexing errors, updates the types and settings for the indexes, and uses versioned indexes and aliases for each document type. It also adds new scripts to the package.json file for testing and debugging the indexing process. The changes affect the files activity.sync.service.ts, member.sync.service.ts, opensearch.service.ts, types.ts, package.json, and byteLength.ts.
