MDA on Colab example

[IAlibay]

Is your feature request related to a problem? Please describe. This year we've had a lot of GSoC students and newcomers to the project that have preferred to use Colab over a local install to test out MDAnalysis.

Some users have found that using @jaimergp's conda-colab makes this a painless experience. It would be great to have an example of how to do this somewhere in the user guide so that we can point folks to it.

Describe the solution you'd like A notebook example or something of that kind to show how it works. I'm not sure how easy it would be to make it spin out directly into a colab instance.

Hey, I edited the condacolab notebook example to install MDAnalysis and run a little test snippet. Check it here.

Once you are happy with the notebook, it can be added to a GitHub repo and then link it through the URL API, like I am doing in this repository (notice the links in the "Titel" column).
