npm shim is not used when running the npm command from a script

[Adrian-Baran-GY]

Describe the bug

When running npm command from a script by using childProcess.execSync ~/.vite-plus/js_runtime/node/22.22.0/bin/npm is used instead of ~/.vite-plus/bin/npm, becuse ~/.vite-plus/js_runtime/node/22.22.0/bin is added before /home/ch4cha/.vite-plus/bin in the PATH. Is this expected behaviour? This is confusing as the output from npm --version command and childProcess.execSync("which npm", { cwd: projectDir, encoding: "utf-8", stdio: "pipe" }) differs.

Reproduction

Steps to reproduce

Given following package.json:

{
  "name": "test",
  "version": "1.0.0",
  "type": "module",
  "devEngines": {
    "packageManager": {
      "name": "npm",
      "version": "11.17.0",
      "onFail": "download"
    },
    "runtime": {
      "name": "node",
      "version": "22.22.0",
      "onFail": "download"
    }
  }
}

we have:

npm --version
# 11.17.0
which npm
# ~/.vite-plus/bin/npm

which is expected.

Given index.js:

import childProcess from "node:child_process";
import path from "node:path";

const projectDir = path.resolve(import.meta.dirname, ".");

try {
  const output = childProcess.execSync(`which npm`, {
    cwd: projectDir,
    encoding: "utf-8",
    stdio: "pipe",
  });
  console.log(output);
} catch (error) {
  console.error(String(error));
}

try {
  const output = childProcess.execSync(`npm --version`, {
    cwd: projectDir,
    encoding: "utf-8",
    stdio: "pipe",
  });
  console.log(output);
} catch (error) {
  console.error(String(error));
}

node index.js output is:

~/.vite-plus/js_runtime/node/22.22.0/bin/npm

11.14.1

npm version reported from the script is 11.14.1 instead of 11.17.0. This is because ~/.vite-plus/js_runtime/node/22.22.0/bin/npm is used instead of ~/.vite-plus/bin/npm. Is this expected? I would assume running commands via the script would use the same env as regular commands in the same directory.
