What is the feature you are requesting?

Allow server owners to use github repos instead of minehut's storage bucket for storing their server while also using github's webhook feature to sync while the server is running.

NOTE: When this is enabled, a new repository should be created, as it makes it possible to move over data without the user downloading it, uploading it to the repository, and then enabling sync

How is this feature useful for Minehut?

Makes contribution easier for server developers, while allowing people to contribute using pull requests (for some servers) & makes it possible to revert to previous commits

By the way, this should use GitHub OAuth and their API to make this process automatic for server owners
