New pydantic model class called Message

[ninabel]

Should be used for all communications between Server, Admin and Players.
It should encapsulate any data going anywhere in the system between any party. It will be shared with all the parties so it should go to quiz-common.

Now we send sometimes string and sometimes a dict over the network (for example sending 'y' form admin to server: https://github.com/quiz-cli/quiz-admin/blob/main/src/quiz_admin/__main__.py#L40)

This logic of parsing data should be part of the Message class: https://github.com/quiz-cli/quiz-client/blob/main/src/quiz_client/__main__.py#L40-L48

This is also sending of some unstructured dict to the network: https://github.com/quiz-cli/quiz-client/blob/main/src/quiz_client/__main__.py#L33

This is also some parsing logic (parse JSON. No? Print the text): https://github.com/quiz-cli/quiz-admin/blob/main/src/quiz_admin/__main__.py#L48-L51

We have to unify it all and send only JSON dict to the websocket every time.

I'd like to take this on. I'll add a pydantic model to unify all websocket communications across the quiz components.
