Revert issue #25687 (Docs Display Hiding elements)

Roll back of issue #25687

docs/4.0/utilities/display.md
line 54, the example, now is:

To show an element only on a given interval of screen sizes you can combine one .d-*-none class with a .d-*-* class, for example .d-none .d-md-block .d-xl-block will hide the element for all screen sizes except on medium and large devices.
but also except on extra large devices

But has to be rolled back to:

To show an element only on a given interval of screen sizes you can combine one .d-*-none class with a .d-*-* class, for example .d-none .d-md-block .d-xl-none will hide the element for all screen sizes except on medium and large devices.

It will be visible on medium (md) and large (lg) devices and invisible on extra large (xl) devices
