Note

Low Risk
Low risk: version metadata updates only (package versions, swagger/appVersion strings, and release script help text) with no functional logic changes.

Overview
Updates RedisInsight’s reported/released version to 3.4.0 across the repo.

This bumps the API and desktop package versions, updates the backend Swagger info.version and default appVersion, and adjusts the release Docker script help text to reference 3.4.0.
