Surprisingly strict node requirement in engines in package.json

https://github.com/aws/constructs/blob/10.x/package.json says:
```
"engines": {
  "node": ">= 14.17.0"
},
```
Does `constructs` actually need >= 14.17.0, or will older versions work? Could it be relaxed to just >= 14, or are there known issues with older node versions?
