fix(translations): correct i18n dynamic variable name for 'movingFromFolder'

[anyuj]

The i18n namespace movingFromFolder's second dynamic variable name should be {{fromFolder}}, but lots of locales use {{folderName}}, and it will fail to get the value, because it is supposed to be fromFolder.

There is also some minor optimization for Folder related translation of zh.ts included inside.
