DOC: Add version query param to JupyterLite URL

[thewtex]

This attempts to add more cache refreshing so the latest version of the notebook / JupyterLite deployment is retrieved.

However, testing locally, it did provide an updated notebook for me with Chrome, npm's http-server.

Unfortunately, it didn't work for me, I think the caching is not in the browser, but it's in the jupyterlite storage layer (implemented via localForage I guess: https://jupyterlite.readthedocs.io/en/latest/howto/configure/storage.html).

With the Imjoy extension, we support load=raw github/gist url and open=1 but it seems failing for your file. The one worked is: https://jupyter.imjoy.io/lab/index.html?load=https://gist.github.com/oeway/391b4352ea57b5682366ce3dc2fa9174&open=1

With load= and open=, we make sure it loaded directly from the url, not the local storage, however, it doesn't work for the moment, strangely for this particular file.

I think the bug is coming from the file browser in jupyterlab, I just filed an issue here: jupyterlab/jupyterlab#14194
