pygame-ce

### Problem
- the pygame-ce package is in pyodide but,:
- https://pyodide.org/en/latest/usage/packages-in-pyodide.html
- https://github.com/pyodide/pyodide/issues/289
- https://pyga.me/docs/ > `# Example file showing a circle moving on screen` doesn't yet work if pasted into a JupyterLite notebook cell

### Proposed Solution
* how to run pygame-ce with JupyterLite notebooks

### Additional context

Start with the linked pygame-ce documentation example and the Pyodide package references, then investigate how the JupyterLite pyodide-kernel currently runs Python packages. The work is complete when the referenced moving-circle example runs in a JupyterLite notebook; the issue does not name a source file or test to update.
