feat(loader): use new ExtensionLoader

[mharrisb1]

Needed to move over to using duckdb/duckdb#17772 to get this working with DuckDB v1.3.2

[Copilot]

Pull Request Overview

This PR migrates the gsheets extension from using the legacy DuckDB extension loading interface to the new ExtensionLoader API, required for compatibility with DuckDB v1.3.2. The changes replace DatabaseInstance parameters with ExtensionLoader and update the extension initialization pattern.

• Updates function signatures to use ExtensionLoader instead of DatabaseInstance
• Replaces ExtensionUtil function calls with direct loader method calls
• Modernizes the extension entry point to use DUCKDB_CPP_EXTENSION_ENTRY macro
