feat: GitHub Webhooks middleware

[oscarvz]

Introduces middleware that allows you to receive and process GitHub Webhooks events in your Hono application.
It conveniently validates the incoming requests and provides you with a simple API to handle the events.

Usage

import { Hono } from 'hono'
import { gitHubWebhooksMiddleware } from '@hono/github-webhooks'

type Env = {
  GITHUB_WEBHOOK_SECRET: string
}

const app = new Hono<{ Bindings: Env }>()

app.use('/webhook', gitHubWebhooksMiddleware())

app.post('/webhook', async (c) => {
  const webhooks = c.get('webhooks') /* const webhooks = c.var.webhooks */

  webhooks.on('star.created', async ({ id, name, payload }) => {
    // handle star creation here
  })

  webhooks.on('issues.opened', async ({ id, name, payload }) => {
    // handle opened issue here
  })
})

Hi @oscarvz

Sorry for the late reply. Looks good. I think it will be helpful if you write this as an example on "Examples" in our doc like the "Stripe Webhook": https://hono.dev/examples/stripe-webhook

Maintaining middleware is harder than updating documentation, so I think it's better to make it a document than adding the middleware to this repo.
