TIMESTAMPTZ type causes test failure due to missing pytz dependency

[proudust]

When using TIMESTAMPTZ type in an extension, running tests with make test fails due to a missing pytz Python module dependency.
I think it would be better to make sure that pytz is also installed by make configure.

Steps to Reproduce:

1. Implement the extension to use TIMESTAMPTZ type (see proudust/extension-template-rs:pytz-missing)
2. Run make test

Expected Behavior:
Tests should run successfully without dependency errors.

Actual Behavior:
Test fails with the following error:

duckdb.duckdb.InvalidInputException: Invalid Input Error: Required module 'pytz' failed to import, due to the following Python exception:
ModuleNotFoundError: No module named 'pytz'
