Next.js does not bundle necessary JSON files in ESM output

### Link to the code that reproduces this issue https://github.com/sofisl/debug-tasks-next.js ### To Reproduce 1. Clone the repo listed above, 2. In [this line](https://github.com/sofisl/debug-tasks-next.js/blob/main/src/pages/index.tsx#L9), replace credentials with a credentials key from google cloud platform (following these instructions): https://cloud.google.com/iam/docs/keys-create-delete. Make sure your service account has access to Google Cloud Tasks in your gcp project, and that it is enabled: https://cloud.google.com/iam/docs/manage-access-service-accounts 3. In [this line](https://github.com/sofisl/debug-tasks-next.js/blob/3ad0d927792a7d291f494f71641a2393f7f182bf/src/pages/index.tsx#L10), replace with your project in the format: `projects/PROJECT_ID/locations/LOCATION_ID` 4. Run npm i && npx next build && node .next/standalone/server.js, and you should see an error. Let me know if you need help getting a google cloud project/key, I work on the client libraries there and can help with the right debugging. ### Current vs. Expected behavior There is a server error. If it works, you should get the basic Next.js page (after running the create script), and you should be able to listQueues in google cloud tasks in your terminal. This is the error: ``` ✓ Ready in 82ms ⨯ Error: Cannot find module '/Users/sofialeon/my-app2/.next/standalone/node_modules/@google-cloud/tasks/build/esm/src/v2/cloud_tasks_client_config.json' Require stack: - /Users/sofialeon/my-app2/.next/standalone/node_modules/@google-cloud/tasks/build/esm/src/json-helper.cjs at Module._resolveFilename (node:internal/modules/cjs/loader:1082:15) at /Users/sofialeon/my-app2/.next/standalone/node_modules/next/dist/server/require-hook.js:55:36 at Module._load (node:internal/modules/cjs/loader:928:27) at Module.require (node:internal/modules/cjs/loader:1149:19) at mod.require (/Users/sofialeon/my-app2/.next/standalone/node_modules/next/dist/server/require-hook.js:65:28) at require…
