Setting up the Deepl subscription for automatic translation

To use the new feature of automatic translation of slides with DeepL you need a subscription, which also comes with costs. Continuing, you can find a screenshot from DeepL's homepage about the required DeepL API Pro subscription, which is necessary for our automatic translation integration. This means that in addition to the monthly 5.49$ cost, there are also the 25$ per 1,000,000 characters.
The button for translation will only appear after the configuration has been done.
