[IMP] web_widget_numeric_step: throttle update calls when scrolling on field

Before this changes, when scrolling on a field, the price update was collapsed because lots of calls to the function was made in a few seconds.

With this changes, the field update, when using the scroll is limited to 1 each 0,1 seconds and the info is updated correctly.
