Created --reset-key flag to update OpenAI key

[Ismail-Ben]

Resolves: #30

Added --reset-key flag to update OPENAI_API_KEY in .sgptrc file. Also verified with a dummy chat completion that the newly inputted key works.

Sample output with 2 non-valid keys followed by a real key:

@TheR1D Any suggested changes to get this in?

I think this option doesn't align with prioritized environment variables in config now, since we can't reset user exported OPENAI_API_KEY. But we could add better error handling into client._request simply checking respone status code for 403/401 printing the error text and raising Exit with error raise typer.Exit(code=1).

I've moved the error handling to client._request as suggested.

As for the reset functionality I added a note to the "help" section of the command as a reminder that the environment variable will still be prioritized. I still believe having a --reset-key option is worthwhile as I would've liked to use it myself when first trying the tool. Instead of having to navigate to the .sgptrc file and update it manually it would've been nice to have this command.

The config.get() function properly prioritizes the use of the env key if it exists so updating the .sgptrc file wouldn't change this behavior. In the case that a user runs this command while already having the env variable, I highlight in yellow that their env key will still be used.

User updates key with env variable defined:

No env variable defined, and fake key:

Let me know what you think @TheR1D . Thanks!

It is very common in CLI applications to use runtime configuration file or ENV variables to set API keys (without having dedicated CLI options to reset some of config values). Please remove reset key option, if we show user proper message, it is clear how to reset it.

Adjusted to reflect @TheR1D 's comments. When using an invalid key the output now looks like:
