[Feature Request]: Enhance mv command to relocate (or message) graphics more gracefully

[karenzone]

Prerequisites

• I have searched existing issues to ensure this feature hasn't already been requested
• I have tested using the latest version of docs-builder

What problem are you trying to solve?

I used the amazing new mv command to move some files around.
After moving files, I removed them from the origin toc.yml, and added them to the destination toc.yml.
The PR is still failing docs CI. PR is here: elastic/docs-content#361

From @colleenmcginnis: "It looks like maybe mv doesn't update image paths, which are relative".
That assessment seems very much inline with the console errors I'm seeing.

Proposed Solution

Enhance the mv command to handle images in relative paths, or at a minimum, enhance messaging to point to problems and provide tips for resolving manually.

There's a chance that I used the mv command in a way that threw of the results.

I ran this command from my docs-content directory:
../tools/docs-builder mv ./raw-migrated-files/kibana/kibana/introduction.md ./get-started/introduction.md
