Renamed to ChatbotsPlace

Originally created to be a place to share prompts, we see that most users are just using our product to use the chatbots, so we have renamed PromptsZone to ChatbotsPlace.

Additionally, we are releasing a Chrome extension (https://chrome.google.com/webstore/detail/chatbotsplace-all-in-one/cbapcdnkcgiajboppakkhjmdolbkinge) to make it more convenient to use.
