chore: drop support for Node 12 (#3547)

Upgrade the minimal required node release to 14.x, since Node 12 has been end-of-life since `2022-04-01`. This allows us to upgrade our TypeScript `target` from `ES2019` to `ES2020` (native support for nullish-coalescing and optional chaining, among other things). Removed the `node12` entries from the various test matrices and stop publishing `node12` tags for `jsii/superchain`. BREAKING CHANGE: Beginning with this release, jsii packages no longer support node 12. Users should migrate to a supported node release (14.x, 16.x, or 18.x).
