Remove api key

[jyotiska]

Removed api key from the google_stt.py to prevent others from abusing the API_key.

It could be worth adding the API key to the config file :)

It'd be nice if there was some sort of public key that we could use for the entire app, especially for people that don't have keys (like me). But, I think if its possible to abuse the key, good pr. 👍

+1. You should also give a prompt if API key is not available and yeah a config file would be great.

My suggestion is - do not expose your own API key to public. People should use their own API key if they want to use or build something with this app. I do not think google will let us use one universal public API key for this app. So, for now, let users use their own API key.

That's what I'm saying. I just want that let users put API key in a config
file rather than the source code.

There is already a config fille which you can use. +1 for an exception if the user does not have an API key :)
