ReferenceError: require is not defined

when running tests on the js/node target, after moving from kotlin 1.9.21 to 2.0.0.
• The error does not occur when running on the js/browser target.
• The error didn't exist on kotlin 1.9.21
• I'm targeting ES modules (useEsModules())

This seems to be caused by the following line - https://github.com/ktorio/ktor/blob/main/ktor-client/ktor-client-core/js/src/io/ktor/client/engine/js/compatibility/Utils.kt#L51C34-L51C69
When packaging the app using ESM modules, the require function is not available in the module scope.
