Update index.md

The piece in the docs regarding adding a value to the list of common languages is not valid anymore.

SS4 uses the php-intl extension,  so before adding an extra locale, the user needs to check whether the installed ICU lib on the server supports it.

If that is the case,  the locale can added through the config system by adding a piece of yaml.

### Language Names ### Adding locales
SilverStripe comes with a built-in list of common languages, listed by locale and region. SilverStripe now uses the php-intl extension. Before adding an extra locale, make sure the ICU library on your server supports it (see https://www.php.net/manual/en/resourcebundle.locales.php for more info).
They can be accessed via the `i18n.common_languages` and `i18n.common_locales` [config setting](/developer_guides/configuration).
They can be accessed via the `SilverStripe\i18n\Data\Intl\IntlLocales.locales` [config setting](/developer_guides/configuration).
In order to add a value, add the following to your `config.yml`: In order to add a value, add the following to your `config.yml`:
```yml ```yml
SilverStripe\i18n\i18n: SilverStripe\i18n\Data\Intl\IntlLocales:
common_locales: locales:
de_CGN: fr_LU: French (Luxembourg)
name: German (Cologne)
native: Kölsch
``` ```
Similarly, to change an existing language label, you can overwrite one of these keys:
```yml
SilverStripe\i18n\i18n:
common_locales:
en_NZ:
native: Niu Zillund
```
