Demo zips from Documents are Unusable as is. about stone-soup

[GadgetSteve]

Suggestion - since the individual demo pages do include the links to the required downloads and mentions of the additional libraries a note to see those pages on the page with the zips might be a way to resolve this at least partially.

Thanks @GadgetSteve

The ZIP file generation is done by sphinx-gallery so may have to see whether there is way to include other files.

As you suggest, a note with ZIPs may be an option to at least highlight that additional files/libraries are needed to run the demos.

We've also designed the demos (and other examples/tutorials) to run as Notebooks, so may be better removing download of the .py files.
