Make GPT4FREE support Python 3.8

[henrik-z4]

Ubuntu 20.04 and lots of other Linux distros are shipped with Python 3.8 preinstalled and they come with apt repos that only have Python 3.8 and not the newest version of python. Uninstalling Python 3.8 ruins the entire operating system, so people are forced to side install the newest version and make it work. Updating python for gpt4free and then dealing with bugs that appear is a nightmare, for me and for other people I met who use this. Moreover, lots of people use their own VPS to store gpt4free. Usually, a VPS comes with Ubuntu 20.04 with Python 3.8 preinstalled. It's very frustrating to make the sideloaded newer version of python work with g4f, as it results in many errors that you should deal with overnight.

I'm not a professional developer yet, but Python 3.8 should have everything for gpt4free to function properly, some changes need to be done to the code though.

For example, you can literally make Bing provider work on Python 3.8 and not throw an error by making a small change to the code in Bing.py, lines 412-419:

'message': Defaults.location | {
                    'author': 'user',
                    'inputMethod': 'Keyboard',
                    'text': prompt,
                    'messageType': 'Chat',
                    'requestId': request_id,
                    'messageId': request_id,
                },

Change the | operator to this:

'message': {**Defaults.location, **{
                    'author': 'user',
                    'inputMethod': 'Keyboard',
                    'text': prompt,
                    'messageType': 'Chat',
                    'requestId': request_id,
                    'messageId': request_id,
                }},

And now it works perfectly fine with Python 3.8

Would throw an error Exception has occurred: TypeError: unsupported operand type(s) for |: 'dict' and 'dict'" before though

Correct me if I'm wrong, but I think it might be beneficial to create a version of gpt4free (maybe with a bit limited functionality) that can operate on Python 3.8. This will make lives of dozens and (probably) hundreds of people much easier.
