`i18n` type doesn't work

When committing with `i18n` as the type, no emoji is added. It doesn't work even if manually added to the config:

```js
{ code: 'i18n', gitmoji: 'globe_with_meridians' }
```

If that gitmoji is added to something else, it works, e.g.:

```js
{ code: 'build', gitmoji: 'globe_with_meridians' },
```
