`npm run <script>` is not using provided interpreter

[samuliasmala]

What's going wrong?

When starting an app in fork mode using npm run command, the Node.JS version from the current shell is used instead of the version provided by the --interpreter parameter.

How could we reproduce this issue?

// package.json
"scripts": {
    "start": "node app.js"
  },

// app.js
console.log('Using Node.JS version ' + process.version);

$ pm2 -v
5.2.0

$ node -v
v16.16.0

$ pm2 start app.js
Using Node.JS version v16.16.0

$ pm2 --interpreter=node@16.10.0 start app.js
Using Node.JS version v16.10.0

$ pm2 --interpreter=node@16.10.0 start npm -- run start
Using Node.JS version v16.16.0

In the last command I was expecting to get the provided version v16.10.0. I'd be happy to create a PR if guided to right direction to solve this. Workarounds are also appreciated.
