[qlife1146]

I added untranslated parts, corrected typos, and translated them more intuitively.

The code has been modified a lot because of prettier. I'm sorry.

Thank you so much! @qlife1146

• Korean translation: hi! @msc9533 @LYHyoung have look maybe?😳 (we are most popular in Korea out of all countries)

• Youtube API: [youtube API independence] (+Required update:Videos Count & Age) #1452 these are our options yet.

• Code-beautification: " vs ' : How did you do it? Shouldn't it be consistent for the whole project? ( could do this for the whole project. Also considering to replace " and \' within the same strings...).

Thanks :)

As for Code-beautification, I use prettier, which is the extension of vscode, and all of the ""s have been changed.
