Drop support for Node 12

[BitForger]

As noted in the node release schedule, It drops out of support at the end of April. This serves as a notice that support will also be dropped for node 12 at that time. Barrelsby may or may not continue to work on node 12 after that point in time.

👍

I think the main thing impacting the node version will be which version of ES syntax the TypeScript compiler generates. If we drop support for node v12, we could potentially update that: https://github.com/microsoft/TypeScript/wiki/Node-Target-Mapping.

That should also be fairly easy to revert in the event that anybody desperately needs to build it for an earlier version.

I guess node v17 can go in this list as well? https://github.com/bencoveney/barrelsby/blob/v2.3.2/.github/workflows/node.js.yml#L19
