Bug description

Error when running using the custom build script and including "effect-cards".

Example build config:

import {
  parseSwiperBuildModulesEnv
} from './utils/helper.js';

const envBuildModules = parseSwiperBuildModulesEnv();

export const modules = envBuildModules || [
  'navigation',
  'effect-cards'
];

export default {
  modules,
};

After running npm run build:prod (using Node 20.10.0) I get the following error:

Error [RollupError]: Could not resolve "../shared/swiper-effect-utils.mjs" from "dist/modules/effect-cards.mjs"

    'C:\\www\\swiper-git\\dist\\modules\\effect-cards.mjs',
    'C:\\www\\swiper-git\\dist\\shared\\utils.mjs'
  ]
}
