Ability to exclude diff signs from "changes" copied contents

[teocns]

Is your feature request related to a problem? Please describe.

Copying (<C-o>) from the "changes" panel adds + and - symbols on the first column of each line as diff contents are copied.

Describe the solution you'd like

To optionally enable / disable including diff signs in the copy buffer, or the ability to bind such filtered copy mode to an other key-mapping different than <C-o>

I need this because currently its a basis of my development workflow, specifically when looking at ai-generated commits in my codebase, I begin to review the diff from the end of the file, selecting relevant lines to clipboard (Ctrl+O) then switching back and forth between lazygit and helix editor (Cmd+`) where I jump to the line mentioned in diff (g+number) and replace it (X d Cmd+v)

Then, to get rid of + symbol, I have to do additionally (X s Enter d), and I hope this enhancement can relieve me from this additional step.
