ionic serve stuck on "Waiting for connectivity with react-scripts" with Node v18

**Description:**

Node v18.12.1 is the current LTS version. Running `ionic serve` in an Ionic React project created by the Ionic CLI keeps logging
```
[INFO] Waiting for connectivity with react-scripts...
```
and as a result live reload doesn't work.

The exact same project runs fine with Node v16.18.1.

**Steps to Reproduce:**

Simply create a new Ionic React project and start it
```
ionic start my-app blank --type=react
cd my-app
ionic serve
```

**Output:**

```
% ionic serve
> react-scripts start

**Other Information:**

In the Ionic Forum: [[INFO] Waiting for connectivity with react-scripts](https://forum.ionicframework.com/t/info-waiting-for-connectivity-with-react-scripts/221876)

Reproduce the issue with a new Ionic React project using `ionic start my-app blank --type=react`, then run `ionic serve` under Node v18.12.1 and compare with Node v16.18.1. Start at the `ionic serve` and `react-scripts` interaction; done means the connectivity wait no longer repeats and live reload works on Node 18.
