feat: support wrangler.json{,c}

[franklin-tina]

• Add support for the new experimental wrangler.json and wrangler.jsonc formats
• Update wrangler to version 3.100.0

I tested this locally by:

1. deleting the original wrangler.toml file
2. creating a wrangler.json or wrangler.jsonc file with the following content:

{
  "compatibility_date": "2022-07-12",
  "kv_namespaces": [
    {
      "binding": "KV",
      "id": "<KV_ID>"
    },
    {
      "binding": "KV2", // <--- I added this.
      "id": "<KV2_ID>"
    }
  ],
  "r2_buckets": [
    {
      "binding": "BLOB",
      "bucket_name": "default"
    }
  ]
}

after running the dev:nitro command, opening the local dev server, I was able to read the values from the new config:

Keys of cloudflare: request, env, context

Keys of cloudflare.env: KV, KV2, BLOB

Colo: YXE

typeof cloudflare.context.waitUntil: function

Before creating this PR, I confirmed the new wrangler config format works by manually setting the configPath value to wrangler.jsonc (or wrangler.json) in my nuxt.config.ts file:

export default defineNuxtConfig({
  // stuff...
  nitro: {
    preset: "cloudflare-module",
    cloudflareDev: {
      configPath: "wrangler.jsonc",
    }
  },
})
