WebSerial flasher fails due to missing 'ssl' Python library

The problem

When attempting to flash a SkyConnect via the WebSerial updater, the following is seen in browser JS console. It seems that the ssl library needs to be manually installed, as it's not bundled with pyodide.

pyodide.asm.js:10 Uncaught (in promise) PythonError: Traceback (most recent call last):

ModuleNotFoundError: The module 'ssl' is unvendored from the Python standard library in the Pyodide distribution.
You can install it by calling:
  await micropip.install("ssl") in Python, or
  await pyodide.loadPackage("ssl") in JavaScript
See https://pyodide.org/en/stable/usage/loading-packages.html for more details.
