Update Snowflake extension descriptor with latest stable and main branch commits

- Update ref to stable branch commit 9f5f549 (v1.3.2)
- Update ref_next to main branch commit c681627 (v1.4.0)
- Add comprehensive install_notes section highlighting ADBC driver requirement
- Include platform-specific driver placement paths for quick reference
- Add direct link to detailed installation documentation
- Ensure users are properly informed about prerequisite driver setup

The extension now points to the latest stable release with updated documentation
that includes consolidated platform-specific installation instructions and
improved Windows support with wget and zip file handling.

Installation notes now clearly communicate:
- ADBC driver is required and not included in extension package
- Platform-specific DuckDB extension directory paths
- Link to comprehensive setup documentation at:
  https://github.com/iqea-ai/duckdb-snowflake#adbc-driver-setup

This addresses the need for users to manually install the libadbc_driver_snowflake.so
file in the correct DuckDB extensions directory before using the Snowflake extension.
