Add holding opt/alt for fast scrolling (#31056)

Browse source 
Fixes #14612

This was a feature I dearly missed from VSCode, so adding this helped me
migrate to Zed without disrupting my workflow. I found that `4.0` was a
nice goldilocks multiplier and felt close/the same as the speed in
VSCode.

Release Notes:

- Added faster scrolling in the editor while holding opt/alt
