BACKLOG-22972: Fix fs import

[baptistegrimaud]

JIRA

https://jira.jahia.org/browse/BACKLOG-22972

Description

Fix the import (use require instead of import) of the "fs" module, as it causes the following error:

Run yarn jahia-pack
/__w/npm-create-module/npm-create-module/node_modules/@jahia/scripts/pack-utility.js:1
import fs from "fs";
^^^^^^

SyntaxError: Cannot use import statement outside a module
