[docs] screenshot still contains project-cleanup

[Deleted user]

Thank you for building this tool!
I need to watch my disk usage so this makes it easy.
I did notice the screenshot still refers to project-cleanup:

For consistency we should update the screenshot to show the latest output. If you don't care about the terminal style, I can screenshot mine and submit a PR.

Apologies for the delay, it seems like this issue slipped under the radar. I welcome a PR to update the screenshot, if you're still interested in contributing. If not I'll probably get around to updating it at some point, but it's not a priority.
