No Python Channel in Web

Testing #18964

Instructions specify to verify output in the Python output channel, but no channel seems to exist even though in-file intellisense seems to be working and the Python Language Server channel does exist.

After poking around with it, this behaviour is expected. The Python extension will load in vscode.dev, but we don't start up anything (no interpreter support), so there won't be an output channel. Sorry for the confusion 😔
