Failed to resolve JSON files when using npm specifiers

[kidonng]

Deno version: 1.26.0

$ deno run -A --unstable npm:xo --help
error: Expected ';', '}' or <eof> at file:///home/codespace/.cache/deno/npm/registry.npmjs.org/globals/13.17.0/globals.json:2:12

According to the README, the globals package contains a plain JSON file and is used by ESLint. The issue seems to be related to JSON resolution (it seems like the resolver treats the JSON as a ES module), but it's just my best guess.

The xo package has a lot of dependencies so it's definitely not a minimal reproduction. Pardon me for not having a better one.

Simpler reproduction:

import globals from "npm:globals";

deno run -A --unstable test.js
error: Expected ';', '}' or <eof> at file:///Users/ib/Library/Caches/deno/npm/registry.npmjs.org/globals/13.17.0/globals.json:2:12

I'm also running into this issue in Deno 1.31.1
