New feature: sharing Data Sources across workspaces

Tinybird has introduced a new feature that allows users to share Data Sources across different workspaces in a read-only mode, addressing customer demands for data reuse across projects and environments without repeated data ingestion. This feature supports teams in either reusing data for different projects such as real-time dashboards and alerts or separating data management responsibilities among team members. Users can share Data Sources with workspaces they have access to, using workspace names or IDs, and track sharing activity including who shared what data and when. Shared Data Sources are visually distinguishable with a special icon, and users can create Pipes or Materialized Views from them. Notifications are sent via email when changes occur to shared Data Sources, such as renaming or deletion, and users are informed of the shared status when listing Data Sources. While the feature currently does not support sharing through the CLI, it allows access to specific logs, but read-only users cannot view data quarantines.
