Make it really easy to install the examples locally

[MarcSkovMadsen]

I've been updating the README https://github.com/holoviz/hvplot/pull/817 and thinking about what would be helpful for potential new users. I believe being able to install the example notebooks locally and spin them up in Jupyter easily would be very beneficial.

You can do it with git clone ... and then manually navigate. But that will clone everything and you would have to navigate a bit.

Instead I would propose some command in the terminal like

hvplot examples

and then a description of this process. For example under installation instructions.

This would be similar to how Panel works.

Yes actually there's bits of code in the repo that should allow to do that, except that the hvplot entry point isn't configured.
