- Implemented a build script to compile i18n files and copy them to the docs directory.
- Added compiled i18n files for Arabic, Czech, Spanish, Persian, French, Indonesian, Polish, Russian, Turkish, Vietnamese, and Traditional Chinese.
- Created an HTML file to demonstrate the usage of Artplayer with i18n support, including language options and a sample video.
