Dont create image-label in image-label

[alanocallaghan]

The previous formulation results in:

"image-label": {"image-label" : { [...]}}

which is obviously unintentional and contrary to the spec

@alanocallaghan thanks for the PR! Is it intentional that the files changed here only include the demo Jupyter notebook? 🤔

I assumed it was just a typo in the example code from the docs; I'm not sure where else it ought to change?
