Compiled executable failed to find modules from custom npm registry containing subpath

Version: Deno 2.0.3

I have encountered this issue while working with a custom npm registry such as JFrog npm-registry. While Deno successfully caches, and executes scripts respecting the NPM_CONFIG_REGISTRY environment variable, compiling the script into an executable results in an ERR_MODULE_NOT_FOUND error for npm modules.

Steps to reproduce

the example was taken from the blog post, I was running Deno 2.0.3 in blank GitHub codespace (Linux), with custom public npm registry mirror:

$ export NPM_CONFIG_REGISTRY=http://mirrors.tencent.com/npm/

$ cat main.ts
import { say } from "npm:cowsay@1.5.0";
console.log(say({ text: "Hello from Deno!" }));

$ deno run --allow-read main.ts
 __________________

                ||----w |
                ||     ||

$ deno compile --allow-read -o main main.ts
Compile file:///workspaces/codespaces-blank/main.ts to main

$ ./main
error: [ERR_MODULE_NOT_FOUND] Cannot find module 'file:///tmp/deno-compile-main/.deno_compile_node_modules/localhost/cowsay/1.5.0/index.js' imported from 'file:///tmp/deno-compile-main/codespaces-blank/main.ts'

Additional info:

I found that using custom npm registry like $ export NPM_CONFIG_REGISTRY=http://registry.npm.taobao.org would work without issues. This leads me to suspect that the problem may be related to how Deno compile handles npm modules located under a subpath (e.g. http://custom-registry.com/path/to/npm/)
