Cannot specify cloud file string using ES Module

New Issue Checklist

• I am not disclosing a vulnerability.
• I am not just asking a question.
• I have searched through existing issues.
• I can reproduce the issue with the latest version of Parse Server.

Issue Description

When using Parse Server with "type": "module", it is not possible to set a cloud string, as it returns Must use import to load ES Module.

Steps to reproduce

Create a Parse Server with "type": "module" (such as https://github.com/parse-community/parse-server-example/pull/400), set cloud file string

Actual Outcome

Error: Must use import to load ES Module: /Users/daniel/GitHub/parse-server-example/cloud/main.js require() of ES modules is not supported.

Expected Outcome

Cloud function to work

Workaround

() => import('./cloud/main.js'),

Environment

Server

• Parse Server version: 4.10.3
• Operating system: MacOS
• Local or remote host (AWS, Azure, Google Cloud, Heroku, Digital Ocean, etc): Localhost

Reproduce the issue with Parse Server configured as an ES module and a cloud file at cloud/main.js, starting with the cloud file string loading path. Compare the failing require() behavior with the documented dynamic-import workaround; done means the cloud function loads and works without that workaround.
