Convert markdown js code block examples to Jupyter notebooks

The examples we have are brilliant, but it might be nice to put them in an interactive environment so people can try them out live.

What might this look like? Here's an example of our python client tutorial in an interactive environment: https://github.com/intermine/intermine-ws-python-docs/#table-of-contents

here is info on the Jupyter javascript kernel: https://github.com/n-riesco/ijavascript

No source files or tests are named. Start by locating the Markdown JavaScript code examples, then review the linked Python client tutorial and IJavascript information; done means the relevant examples are available as interactive Jupyter notebooks.
