Add a setting to control the vertical and horizontal scroll sensitivity (#10244)

Browse source 
Some people (like myself) use touchpads for development and I find Zed's
default scroll sensitivity to be slower than I like. This change adds a
scroll sensitivity multiplier that allows users to customize the speed
of their scrolling.

Release Notes:

- Added a setting under "scroll_sensitivity" that allows user to control
the scroll sensitivity. This value acts as a multiplier for the
horizontal and vertical scroll speed.
