Remove Python 3.14 from test matrix - incompatible with cocotb

Python 3.14 is still in development (alpha/beta) and causing cocotb simulation tests to fail. The cocotb library and its dependencies are not yet fully compatible with Python 3.14. Tests work correctly on Python 3.10-3.13, which aligns with the project's requirements.
