IDE/Menu: Explicitly specify the word "file" in the recent files menu. Issue #39554

Issue

Many applications work only with one type of file, and they are opened via the File menu, which usually has an Open command and an Open Recent submenu.

But Lazarus, in addition to working with regular files, can work with projects and packages. Each of them requires special functionality, which can be found in the corresponding menu items. There are also separate open commands and a list of recent ones.

However, out of habit, users use the File menu to open ([Ctrl+O]), and also expect to see recent projects in the same menu. This misconception is caused by the vague naming, the ability to open projects as regular XML files, and the !417 (closed) bug...

To reduce confusion, I suggest explicitly naming the File > Open Recent menu as Open Recent File. Then users will be less likely to expect to see a project/package there, and will definitely check the Project/Package menu.

Also, this will make the naming consistent:
