Add a Tour of JupyterLite

[jtpio]

Using https://github.com/jupyterlab-contrib/jupyterlab-tour

This would help guide new users of the JupyterLite interface, and explain that kernels run the browser.

Also explain what the differences between notebooks and consoles are for instance.

Tours are a whacking good idea, and best of all, simple ones can be encoded in JSON (jupyterlab-contrib/jupyterlab-tour#2).

Going beyond the docs for this repo, I'd definitely see making custom tours something that can be added without re-building the app, as could be enabled/built in #41.

That got merged, not sure release timeline, but would give us something concrete to develop #81 around.

In doing docs for that, turns out lab core has a pageConfig.json... perhaps it's worth looking into that, and divesting jupyter-config-data from jupyter-lite.json. I'm thinking any time there is a canonical file, we should use it instead of making up new things... in this case, it doesn't get loaded at runtime, but still...

tour 3.0.1 landed with the settings stuff, so i'll get #94 buttoned up (just validating JSON at this point, I think) and start into #81...

Thanks!

Pasting the ideas mentioned in https://github.com/jtpio/jupyterlite/pull/98#issuecomment-843168648 here for visibility

Also what do you think the JupyterLite tour should cover?

Ain't that the way! Some ideas, out of order:

• highlight the file browser icon

  • Where are my files stored?
  • JupyterLite starts with files hosted along with the application
  • You can upload new files, make copies, and change existing tiles. These are stored in your browser's localStorage or IndexDB
  • If you delete a browser file, or work in Private browsing and close your browser, it's GONE FOR REAL

    • maybe we need a trashlite?

• hilight the file menu

  • If you've used JupyterLite before, there (should) be some things missing here
  • like Download As
  • We hope to support downloading your current JupyterLite site as an archive, though

• For each kernel, as they grow in complexity, we may need their own tour of their notebook

  • how to import libraries
    • or in the case of pyolite, install libraries
    • and why they might not install/import properly
  • specific limitations

Will do some more thinking... also, big dummy me for not doing it when i did the settings PR, but we should be able to put tours in notebook's metadata.

As discussed in #287, we could have 2 different tours in JupyterLite: one for lab and one for retro.
