v2.2.0 - PostgreSQL NULL Array Support and Peer Dependency Update

Enhancements

• Formal support for NULL elements in PostgreSQL integer and text arrays. Values like '{1,NULL,3}'::int[] now correctly deserialize to [1, null, 3]. This behavior is provided by @aws-sdk/client-rds-data 3.1048.0+ and is now documented as a supported feature rather than a known limitation (2a4b4a3)
• Raise @aws-sdk/client-rds-data peer dependency floor from ^3.0.0 to ^3.1048.0 so users on older SDK versions get a peer-dep warning instead of silently running against the known-broken NULL-in-array path (2a4b4a3)

Testing

• Remove stale test.fails() markers on NULL-in-array test cases that now pass with the bumped SDK; drop duplicate copies that previously lived in the "Known Data API Limitations" section (d87a6f6)

CI/CD

• Serialize Integration Tests workflow runs against the shared Aurora cluster via a workflow-level concurrency: block, preventing the "Table doesn't exist" and "relation does not exist" races between simultaneous PR and main-push runs that drop tables out from under each other in afterAll (#172) (a7e40c6)
