Consider bumping the minimum support node version supported by the generated code.

[sbc100]

We currently support generating code that run on node versions all the way back to v10.19 (even though by default we target v16).

There are several reasons to want to drop support for such ancient versions of node. For example: #18235

In #18235 the requirement is for v12, so perhaps we can at least bump to v12? Do we know of any users that still want to run the generated code on node v10 or node v11?
