Korean is missing. (in 2.3.324)

Same symptoms: https://bugs.mojang.com/browse/MCL-22070

Korean is missing in minecraft launcher(2.3.324)'s language setting.

As described in the picture(=k.png), there was Korean in that location, but it disappeared after the update.

As a result, it became impossible to set it in Korean, and the user previously set in Korean was changed to English.

Although it is set to KO-KR like ks.png, it is not displayed in Korean.
