fix: bump release workflow Python from 3.9 to 3.11

dbt-adapters>=1.22.0 requires Python >=3.10, so the release pipeline
was failing during dependency installation.

feat: upgrade to dbt-core 1.10.20 (#5)

- Bump version to 1.10.20 (no adapter code changes needed)
- All 1.10.1-1.10.20 patches are internal fixes with no adapter API changes

feat: upgrade dbt-adapters to >=1.22.0 (#4)

- Fix unit test materialization: pass column_name_to_quoted to
  get_expected_sql (required by dbt-adapters 1.22.x)
- protobuf 6.x works at runtime despite dbt-core 1.10.0 declaring <6.0
