Update README.md

* Fix borderless fullscreen always on top

Don't pass a monitor to glfwSetWindowMonitor(). This avoids setting the flag which keeps the window always on top.

* Update for borderless-windowed always on top bug

Only apply the fix for Windows OS, since that seems to be the only
platform with the issue.

 This is a basic raylib example, it creates a window and draws the text `"Congrats! You created your first window!"` in the middle of the screen. Check this example [running live on web here](https://www.raylib.com/examples/core/loader.html?name=core_basic_window).
