Dynamic Webhook Enum Generation

[0x4007]

Consider dynamically generating the enum file based on the @octokit/rest dependency contents at build/pre run time.

I'd like to avoid using our own enum for events but the problem is that octokit provides only a readonly array of all events or a typescript union type of all events but I haven't figured out how to use them with typebox
