adapter-cloudflare-workers: Configure custom wrangler.toml file name

[ghost]

Describe the problem

My use case requires multiple wrangler.toml files.

The current implementation does not allow for other names other than wrangler.toml.

Describe the proposed solution

Add an option to the adapter to allow changing the default wrangler.toml, like so:

import adapter from '@sveltejs/adapter-cloudflare-workers';

export default {
  kit: {
    adapter: adapter({ config: '<your-wrangler-name>.toml' })
  }
};

Alternatives considered

I have used a script to swap out the wrangler.toml.
