node.js out of date
### Describe The Bug

Similar to #467, I upgraded homebridge-config-ui plugin, and then the webUI was refusing to start with the following error in the logs:

```
[11/17/2022, 12:23:47 AM] [Homebridge UI] SyntaxError: Unexpected token '?'
[11/17/2022, 12:23:47 AM] Homebridge UI] Caught Unhandled Rejection Error :: Details Below
/usr/local/lib/node modules/homebridge-config-ui-x/node modules/fastify/lib/server.js:38
     const hostPath = listenOptions.path ? [listenOptions.path] : [listenOptions.port ?? 0, listenOptions.host ?? 'localhost']
```

Checking into it, seems older version of node don't support the ?? operator. Sure enough, node in this docker container is v12:

```
/usr/local/lib/node_modules/homebridge-config-ui-x/node_modules/fastify/lib # node --version                                                         
v12.13.1  
```

The docker container is up to date, updated both via pulling latest from the registry and by using the Synology package. I've had the docker image set up since 2019, so it seems that the node version isn't being updated from when the container was first created.

Per #467, attempted to update node:

```
/usr/local/lib/node_modules/homebridge-config-ui-x/node_modules/fastify/lib # hb-service update-node

✖ To update Node.js you should pull down the latest version of the oznu/homebridge Docker image.
```

Have already pulled down the latest version a week or so ago when I first tried to upgrade the config-ui plugin and ran into the same problem.
