ARROW-2993: [JS] Document minimum supported NodeJS version

Adds an engine requirement to package.json, and sets engine-strict in project-level npm config

This makes it so that running `npm install` in arrow/js yields the following error:
```
$ node -v
v9.11.2
$ npm install
npm ERR! code ENOTSUP
npm ERR! notsup Unsupported engine for apache-arrow@0.3.0: wanted: {"node":">=10.0"} (current: {"node":"9.11.2","npm":"5.6.0"})
npm ERR! notsup Not compatible with your version of node/npm: apache-arrow@0.3.0
npm ERR! notsup Not compatible with your version of node/npm: apache-arrow@0.3.0
npm ERR! notsup Required: {"node":">=10.0"}
npm ERR! notsup Actual:   {"npm":"5.6.0","node":"9.11.2"}

```

Users should get a similar error when they install an arrow package if they have engine-strict set in their own npm config.
