Bug: Add `baseBuilder` property in `MiniAppManifest` type and let it include in `withValidManifest`

[tawago]

Describe the bug and the steps to reproduce it

When a builder wants to import a mini app, baseBuilder property is required in the farcaster.json.

In the Quick start repository example (https://docs.base.org/mini-apps/quickstart/create-new-miniapp), adding baseBuilder to minikit.config.ts does not reflect the change because it uses withValidManifest in app/.well-known/farcaster.json/route.ts and the property gets filtered out, as a result, preventing the builde import the miniapp.

import { withValidManifest } from "@coinbase/onchainkit/minikit";
import { minikitConfig } from "../../../minikit.config";

export async function GET() {
  return Response.json(withValidManifest(minikitConfig)); // "baseBuilder"  gets lost
}

What's the expected behavior?

withValidManifest should not filter out baseBuilder

What version of the libraries are you using?

@coinbase/onchainkit@1.0.2
