Update the C3 behavior for Cloudflare Workers template

[yusukebe]

Currently, if we create a new Cloudflare Workers project with C3, C3 will add the following code to index.ts:

type Bindings = {
  [key in keyof CloudflareBindings]: CloudflareBindings[key]
}

This snippet does convert interface to type because new Hono() does not accept interface before.

But, since v4.5.0, we can pass an interface to it! We can remove that snippet and pass the CloudflareBindings directly.

I tried this issue at cloudflare/workers-sdk#6481. I think this issue can be closed when the PR is merged.

@yusukebe could I please get a stamp from you on @roottool 's PR 🙏 . Looks good on our side, but since you have more Hono context than I do, I'd feel better if we can get your review as well. It's a fairly straightforward PR so shouldn't be time consuming.

Thank you in advance for your help ❤️
