🐛 Fixed pinch zooming mouse issue (with ctrl key) (#940)

**Fixed the drastic zoom increase decrease on ctrl + mouse scroll.**

The issue was occuring due to the "scale" property in the pinch gesture.
The scale was getting bigger values, leading to more zooming.
What I did was, made sure that maximum scale difference between current
and last value cannot be more than the scaling factor used in
zoomin/zoomout buttons. That is. 0.2
Also, the pinch zoom would work as expected.

### Summary by CodeRabbit

- Improvement: Enhanced zoom precision in the Graph component. This
update allows for more accurate scaling when adjusting the view in the
graph builder. The change ensures that the zoom level adjusts more
precisely, providing a smoother and more controlled user experience when
interacting with graphs.
