qemu-docs: Update options for graphical frontends

The command line options `-ctrl-grab` and `-alt-grab` have been removed
in QEMU 7.1. Instead, use the `-display sdl,grab-mod=<modifiers>` option
to specify the grab modifiers.

+During the graphical emulation, you can use special key combinations from
+the following table to change modes. By default the modifier is Ctrl-Alt
+(used in the table below) which can be changed with ``-display`` suboption
+``mod=`` where appropriate. For example, ``-display sdl,
+grab-mod=lshift-lctrl-lalt`` changes the modifier key to Ctrl-Alt-Shift,
+while ``-display sdl,grab-mod=rctrl`` changes it to the right Ctrl key.
