textinputv3: need to commit() after disable()

https://gitlab.freedesktop.org/wayland/wayland-protocols/-/blob/master/unstable/text-input/text-input-unstable-v3.xml

disable() - Disable Text Input On A Surface

Explicitly disable text input on the current surface (typically
when there is no focus on any text entry inside the surface).

State set with this request is double-buffered. It will get
applied on the next zwp_text_input_v3.commit request.
