Fix ESLint import/prefer-default-export by using only default export

Changed translations.js to only export default (no named export) and
updated all imports to use default import instead of named import.

Files changed:
- client/app/libs/i18n/translations.js: Removed named export
- client/app/bundles/comments/containers/RouterCommentsContainer.jsx: Updated import
- client/app/bundles/comments/containers/NonRouterCommentsContainer.jsx: Updated import
- client/app/bundles/comments/components/SimpleCommentScreen/ror_components/SimpleCommentScreen.jsx: Updated import
