end of Node.js 10 support

[wh0]

Node 10 is no longer maintained, and I'll be looking to start using features that it doesn't have, in this project. I think we'll wait a while to see if Glitch moves over to a later version of Node for its in-container software though.

I think this issue requires an update, Glitch now supports well beyond 10.x all the way to 16.6! This also means dependencies like commander can be updated.

glitch has long supported node higher than 10, but the observation in the issue description was that glitch uses specifically node 10 for some important things. that makes it an appealing target because we know it'll be available in the project containers

Node.js 12 is out of support too now.
