Array translations returned as single result with concatenated string

[krisloekkegaard]

Describe the bug
When submitting an array of strings for translation, I am getting a single TextResult object back, whose text field is a concatenation of all the translations, comma-separated.

The documentation states that a list of TextResult objects should be returned, and this is also the behavior I used to see. I didn't update anything in our code nor update the version of the deepl-node package.

To Reproduce
Steps to reproduce the behavior:

import * as deepl from 'deepl-node';

const translator = new deepl.Translator('***');
const targetLang: deepl.TargetLanguageCode = 'fr';
const results = await translator.translateText(['Hello, world!', 'How are you?'], null, targetLang);
console.log(results);

The output I'm seeing currently is:

[
  {
    text: 'Bonjour le monde, comment allez-vous ?',
    detectedSourceLang: 'en',
    billedCharacters: 26,
    modelTypeUsed: undefined
  }
]

Expected behavior
The result should be an array of TextResult objects, each containing the translated text of the corresponding string from the input array.

The output I was expecting (and was previously getting) is:

[
  {
    text: 'Bonjour le monde',
    detectedSourceLang: 'en',
    ...
  },
  {
    text: 'Comment allez-vous ?',
    detectedSourceLang: 'en',
    ...
  }
]

Closing as I believe this is a duplicate of #66
