Use multiple words for the same emoji

## Feature Request

**Describe the solution you'd like**
To avoid having to create several objects for the same emoji, why not use an array containing all the words?

**New translation file structure**
Before:
```js
{
  name: 'halloween',
  emoji: '🎃',
},
{
  name: 'pumpkin',
  emoji: '🎃',
}
```

After:
```js
{
  name: ['halloween', 'pumpkin'],
  emoji: '🎃',
}
```
