Add option to generate interactive gallery with replite

Proposal

Add an option to use jupyterlite to have make a gallery of interactive examples.

How

Using jupyterlite it’s now possible to have interactive python repl on a webpage without a backing from binder. https://jupyterlite-sphinx.readthedocs.io/en/latest/directives/replite.html provides a :replite: sphinx directive that enables this. Naively I’d expect that replacing the ..code-block:: with :replite might just give automatic interactivity.

There be some work to get examples with multiple code blocks to share the same kernel between them, but even if this was just enabld for examples wiht single code blocks that would be amazing!

updated the link.

“run in jupyterlite” to the bottom next to the download buttons? Or potentially replace the default example rendering with an interactive one?

I think having an option for both would be good!

maybe I can make it open in another window instead of an iframe

Yes, for example ipycanvas does this by providing a badge on the docs landing page: https://ipycanvas.readthedocs.io/en/latest/?badge=latest
