pyodide setup.py - ensure we have correct pyodide_2025_0_wasm32 suffix

Adding extension, but avoiding adding sources as we're not actually building.
As a result build will have a correct suffix `pyodide_2025_0_wasm32.whl` that's pyodide is currently using and this is pyodide is plan to use when it's going to release to PyPI, see https://peps.python.org/pep-0783/
