Intl.NumberFormat signDisplay option displays odd behaviour

### Description

The `signDisplay` option for `Intl.NumberFormat` is bugged and has an odd behaviour. E.g. the option `exceptZero` outputs "`+8,537,71+`" but it should output `+8.537,71 €`. Don't know if this only affects Android.

### Steps to reproduce

1. Create a new React Native application
2. Insert this code somewhere:

```js
{
new Intl.NumberFormat('de-DE', {
style: 'currency',
currency: 'EUR',
maximumFractionDigits: 2,
minimumFractionDigits: 2,
roundingMode: 'floor',
signDisplay: 'exceptZero',
}).format(8537.71)
}
```

3. Start the app on Android

### React Native Version

0.74.4

### Affected Platforms

Runtime - Android
