fix: Chinese translate error for Windows context menu setting (#2396)

### Problem description
In current Chinese translation, "Windows context menu entry" in General
settings has been tranlated to 窗口上下文菜单项. and for Traditional Chinese,
it's 視窗內容功能表項目 (basically the same).

The previous translations were not conveying the correct meaning
associated with the term "Windows context menu entry". They were too
literal and did not clearly describe the functionality related to the
Windows Explorer context menu.

"窗口" in Chinese means a physical window, **not the Microsoft Windows
OS**. The Windows OS is usually referred to as "微软视窗" (rare) or left as
"Windows".

"上下文菜单" is a very "direct" translation of "Context menu" that is hard to
understand for most users. Chinese user usually call it "右键菜单", which is
"Right-Click Menu".

### Implementation description
I've changed it to 添加到文件资源管理器右键菜单 for Simplified Chinese, and
加至檔案總管的環境選單 for Tranditional Chinese.
