Summary

Follow-up to PR #2541 (closes #2536). The CHANGELOG entry only mentioned polygonize(return_type='geopandas'), but the PR description and the implementation are broader: the auto-detected transform is applied inside _scan, so every return_type option (numpy, awkward, geopandas, spatialpandas, geojson) benefits.

This PR rewords the entry to match the PR description and the code, without changing any behaviour.

Test plan

  • CHANGELOG-only change, no code or tests affected.
  • CI green.

The PR description for #2541 notes that the auto-detected transform is
applied inside `_scan`, so every return_type (numpy, awkward, geopandas,
spatialpandas, geojson) benefits. The CHANGELOG entry only mentioned
return_type='geopandas', which understates the fix scope.
