supported locales (array) in .env

PHP Code:

public $supportedLocales = ['en', null, null]; 


.env:

Code:

app.supportedLocales.0 = fr
app.supportedLocales.1 = en
app.supportedLocales.2 = de

---

I don't think there are any cases where the supported locales need to be changed depending on the environment.

And I don't think we need to use $threshold like [6,8,9] in the config. A single value is sufficient.
