Fix the translation mechanism for the platform dropdown #61
Description
This refers to the translation feature brought in through PR #59.
The translation of the options label fails. Translating the label raises a KeyError when calling 'label': TRANSLATIONS_DICT[k][language], 'value': v} for v, k in list(data_dict.providersTypes.items()). The key that is not recognized is the translation of 'Personal laptop', 'Desktop computer' or 'Local server'.
However, printing 'label': TRANSLATIONS_DICT[k][language], 'value': v} for v, k in list(data_dict.providersTypes.items()) does not raise the error, which is strange.
WARNING: this may happen for the translation of other dropdown options.
