Node 16 MFE update

The latest set of MFEs are now using Node 16 - previously this was up to Node 14. This has caused us a fair amount of issues as the Tutor MFE is using node 12 versions of images.

I was going to locally test a node 16 update and wondered if anyone there was working on updating the tutor mfe plugin to now use node 16. Does the Caddy also need updating to the latest?

Thanks.
