Describe the bug

The Typescript SDK is incompatible with the current runtime since only Nodejs 12 is provided - and the SDK requires a more recent version.

We should install a recent version of Nodejs when creating the runtime rootfs instead of using the version provided by Debian 11 Bullseye.

Installing it from Nodesource looks like a recommended approach:
