[feat]: Add zoom-in binding

[noueii]

Feature Summary

Allow users to zoom in by pressing CTRL +

Problem or Use Case

I wanted to zoom in recently in order to see the UI more clearly.
To my surprise, I found out zooming out is possible but zooming in not.

After spending a lot of time with a zoomed out application, I noticed it is also possible to reset the zoom to the default value.

Proposed Solution

• add a keybinding of CTRL + in order to allow users to zoom in
• add all other zoom related keybinds to the list (currently none are present)

I will take this issue. Please assign it to me.

The zoom-out functionality is present, but zoom-in is missing. I will first check the existing keybinding implementation for zoom-out. Then, I will add a similar binding for CTRL + to zoom in. I will also update the documentation to include all zoom-related keybindings. This should ensure consistency and improve usability.

I am starting to work on this. I will add the CTRL + keybinding for zooming in and update the documentation with all zoom-related keybindings. Let me know if there are any specific requirements or considerations.
