Upgrade DuckDB Version

Change version in:

• bindings/scripts/fetch_libduckdb_linux_amd64_musl.py
• bindings/scripts/fetch_libduckdb_linux_amd64.py
• bindings/scripts/fetch_libduckdb_linux_arm64_musl.py

Also change DuckDB version in package versions.

Check Function Signatures

• node scripts/checkFunctionSignatures.mjs [writeFiles]

Checks for differences between the function signatures in duckdb.h and those declared in duckdb.d.ts and implemented in duckdb_node_bindings.cpp.

Optionally outputs JSON files that can be diff'd.

Useful when upgrading the DuckDB version to detect changes to the C API.
