feat(i18n): add Mods page localization and shared links

- Introduced a new file for Mods page localization with translations for multiple languages (en, de, fr, es, ru, ja).
- Updated existing homepage localization files to include references to the new `gregFramework` terminology.
- Added shared links for knowledge and workflow sections to enhance documentation accessibility across different languages.
