PyTerminal: use Pyodide instead of Python

[WebReflection]

Description

This MR specifically addresses this comment and while everything seems to be fine I'd love to have @hoodmane or @antocuni reading the changes and tell me if this is the best way forward, thank you!

Changes

• drop the Python builtins.input = ... workaround and use Pyodide directly
• update the smoke-test page to be sure everything is fine

Checklist

• All tests pass locally
• I have updated docs/changelog.md
• I have created documentation for this(if applicable)

It seems good to me. What I expect is that now os.write(1, "hello\n") and os.write(2, "world\n") should go to the terminal, while previously they were not redirected.
Maybe it's worth adding an integration test?

Maybe it's worth adding an integration test?

added a test and also witnessed via quick smoke test everything indeed works as expected ... ready for review!
