+Output wrangler.jsonc instead of wrangler.json
+
+The JSONC format allows comments, but otherwise uses standard JSON syntax.
+
+Note that Wrangler is still happy to parse `.json` files with comments (along the lines of `tsconfig.json`), but to prevent confusion and for default compatibility with all IDEs, create-cloudflare will now output `wrangler.jsonc`.
