Enables Auto-GPT to use BingAI to fetch information, utilizing the robust information gathering built into BingAI. This plugin saves time, increases efficiency, and decreases the amount of API calls to OpenAI.

This is a mass message from the AutoGPT core team to all open Plugin-PRs

We're in the process of re-architecting: https://github.com/Significant-Gravitas/Auto-GPT/wiki/Architecting

Please be patient as we work to clean up the AutoGPT core.

If you already have an existing plug-in that’s affected, please message @ntindle on Discord so we can get your plugin spinning on the new architecture.

If you're working on a plugin, please bear in mind that one of our primary goals in re-architecting is to make life MUCH easier for you. We've taken aboard feedback from plugin developers. We're on it, so please give us some time!
