Google Analytics 4 integration

### Describe the issue

Hello, I have attempted to use the lightly documented feature: `GOOGLE_ANALYTICS_ID` -- but the resulting code does not appear to be correct, and does not function. My Google Analytics Console is not able to receive any data with it.

```

(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');

ga('create', 'G-##########', 'auto');
ga('send', 'pageview', {

'dimension1': 'en'
});

```

The Measurement ID has been omitted intentionally.

### I already tried

- [x] I've read and searched [the documentation](https://docs.weblate.org/).
- [x] I've searched for similar filed issues in this repository.

### Steps to reproduce the behavior

1 - Insert Measurement ID into the config
2 - Restart Weblate
3 - No Data is flowing into the GA4 property.

### Expected behavior

Google Analytics can receive data.
