Describe the reason for change

When labeling images, the current zoom behavior is not intuitive, as it's reversed from common applications.
Link to the issue: #6729

label studio:

• ctrl + scroll up == zoom out
• ctrl + scroll down == zoom in

other software:

• ctrl + scroll up == zoom in
• ctrl + scroll down == zoom out

What does this fix?

(if this is a bug fix)

What is the new behavior?

I added a new parameter into the configuration modal “Reverse zoom scroll direction”, so users can toggle to choose which scrolling direction they want.

They could switch to the new setting, or keep using the previous one if they are used to it.

What is the current behavior?

Currently, Ctrl+scroll up zooms out and Ctrl+scroll down zooms in.

What libraries were added/updated?

No new libraries were added or updated.
