ML Metadata 1.21.0

Major Features and Improvements

• Added Python 3.12 and Python 3.13 support.

Breaking Changes

• Removed Python 3.9 support.
• Removed ZetaSQL-based filter_query functionality. The filter_query
  parameter in ListOptions that relied on ZetaSQL for declarative filtering
  has been removed in version 1.21.0. Users should migrate to native lookup
  and lineage APIs (such as get_artifacts_by_uri, get_artifacts_by_context,
  and get_lineage_subgraph) and filter retrieved objects directly in Python.
