Unlimitedgpt

- Added check for platform to use command when on MacOS instead of left control.
- Added `pyperclip` to requirements.txt as it is a required library now.

- Updated selectors yet again.
- Added a smart solution to dismissing the onboarding box that pops out when logged into an account:
- Instead of constantly using XPATHs to click the "Next" buttons and suffering as it sometimes just refuses to click, or when the website updates and the selectors are changed, I came up with the solution of adding an item to the `localStorage` of the ChatGPT website that marks the user as already seen the onboarding popup.
- Instead of the old, hard to maintain way of using XPATHs to get the response from ChatGPT, I've decided to use the copying machanism instead.
- Clicking CTRL + SHIFT + C copies the last response from ChatGPT, so I've used that to our advantage.
- Removed continue generating mechanism as I just couldn't get a single case where there was a need to continue generating as ChatGPT now seems to write a lot more than before in a single message.
- Updated `ChatGPTResponse` object to have a boolean attribute called `failed` which indicates whether the library failed to get the response from ChatGPT Or not.
- Added an element visibility check to the custom `safe_click` function within the driver of UnlimitedGPT.
- Updated `requirements.txt` and the `README.md`.
