Translation source-code-directory-structure.md 100%

Hello everyone
on this occasion I have made a contribution to the translation for the electron project and I have done the translation to 100% on the source-code-directory-structure.md string 560 WORDS

on the project has many structures that are difficult and can not be translated all in indonesian language, there is a common word and we i turn it into indonesian language, it will make the user become confused, so i adjust anything that need to be translated
