Description

In "Check Supported Languages" section, you mentioned we can check the supported languages of each translator by calling the get_supported_languages function as below example.
langs_list = GoogleTranslator().get_supported_languages() # output: [arabic, french, english etc...]

What I Did

Problem1:
I would like to check the language supported list of LingueeTranslator and give a command like this,
langs_list = LingueeTranslator().get_supported_languages()

The VSCode throws an error like below
File "h:\my_prog\deep-translator\deep_translator\base.py", line 84, in _map_language_to_code
raise LanguageNotSupportedException(
deep_translator.exceptions.LanguageNotSupportedException: en --> No support for the provided language.

I also try PonsTranslator like below command, the error is same
langs_list = PonsTranslator().get_supported_languages()

Problem2:
I have tried my pdf file by following command and the content of abc.pdf have more than one page.
translated = GoogleTranslator(source='auto', target='chinese (traditional)').translate_file("abc.pdf")

the result of translated only have first page data, how can I get second and third pages translated data?
Do I need an extra processing to separate pdf file if content over one page?

I was wondering if you could do me a bit of a favor?
