bug#41351: 28.0.50; Cannot customize mouse-drag-and-drop-region-show-tooltip

[David Ponce <da_vid@orange.fr>]

Hello,

The option `mouse-drag-and-drop-region-show-tooltip' cannot be
customized as mentioned in the doc string. Only an integer value can be
entered via customization. The proposed patch below fixed the defcustom
for me.

Thanks!
