[New] Support localization
I use simple methods to support localization.
You can find the language that suits you in the languages folder.
Place yt-dlp-gui.lang in this folder in the same folder as yt-dlp-gui.exe
You can use the English version of the lang file as a template to modify the language you need
If you are willing to share your local language files, you are welcome to provide them to me, and I will be included in the languages
