Binder (using postBuild) was using outdated tutorial notebooks, even after virtualship/main had updated changes. Cached built images were being reused.

Adding a new commit apparently forces binder to rebuild the image and refetch the updated tutorials. (files and path remain same)

Tested with: https://mybinder.org/v2/gh/Parcels-code/virtualship-workspace/460d4011cc996342d2d6779c3a40d96db50d747f?urlpath=lab/tree/welcome.md

(This works for now, but not the most efficient for repeating changes to post-processing tutorial files)

Not ideal to have to make these superfluous commits just to retriever binder build - but if there's no other way then let's do it

@erikvansebille agreed. However, considering binder will be used for course tutorials soon, this seems a quick fix. But i will open an issue and explore options to perhaps automate a new build.
