[Bug]: Import JSON file from npm specifier.

### Problem description

Importing a JSON file from npm specifier package works locally but not in deno deploy.

### Steps to reproduce

1. Add import of json file using npm specifier.
2. When uploading to Deno Deploy/playground this error occurs: `{"type":"error","code":"deploymentFailed","ctx":"The deployment failed: BOOT_FAILURE\n\nExpected a \"JSON\" module but loaded a \"JavaScript\" module."}`

### Expected behavior

json import in deno deploy should work the same way it does locally.

### Environment

Local env where import works is:
deno 1.38.1 (release, x86_64-unknown-linux-gnu)
v8 12.0.267.1
typescript 5.2.2

### Possible solution

_No response_

### Additional context

Using esm.sh instead of npm specifier does work.

I prepared a playground with simplified code to reproduce the issue.
https://dash.deno.com/playground/cova-pg

Start with the linked Deno Deploy playground and reproduce the failure by importing a JSON file through an npm specifier. Compare that deployment with the working esm.sh version; done means the npm-specifier JSON import deploys successfully and behaves like the local run.
