#510

Summary

KDS still uses NodeJS 12 which is no longer maintained or supported. At some point in the future, doubtless Github Actions will cease supporting this, which will cause our Github Actions to break.

We should upgrade to use NodeJS 16 which will require the following sequence of steps:

When this is ready, we will also need to update this Netlify settings

I can do it, let me know when the time comes.

I just gave this another stab - still seems to be some complexity here, I don't know if the kolibri package separation is needed here, but it may make it simpler at the least.
