feat(create-cloudflare): Add support for wrangler.json(c) in templates

[maxwellpeterson]

Fixes WP-1369.

• For external templates, use wrangler.json(c) if it exists instead of wrangler.toml
• All templates in cloudflare/templates use wrangler.json
  • We need to support these templates in C3 before public launch

How to Test

npx https://prerelease-registry.devprod.cloudflare.dev/workers-sdk/runs/12204431707/npm-package-create-cloudflare-7484 --no-auto-update --template=cloudflare/templates/multiplayer-globe-template

cloudflare/templates/multiplayer-globe-template uses wrangler.json instead of wrangler.toml. If you try to use this template with the latest version of C3 it fails because the template doesn't contain a wrangler.toml file:

$ npm create cloudflare@latest -- --template=cloudflare/templates/multiplayer-globe-template

Error: create-cloudflare templates must contain a "wrangler.toml" file
