Add Streamlabs Cloudbot to Stream commands generator

[rediche]

Streamlabs now doesn't only have their chatbot, but also has a built in chatbot in their OBS version. It uses a different way of reading the API. The generator therefore needs to be able to generate the snippet.

Change from radio buttons to dropdown since multiple long word options are going to be present.

The new option should be called Streamlabs Cloudbot

This is blocked due to Streamlabs OBS Chatbot returning [Bad Request / Too Slow] error in chat.

After testing on stream for a few weeks the [Bad Request / Too Slow] still occurs once in a while, but not regularly. That is probably just more down to the backend atm. This issue is no longer blocked.
