Pull request overview

This PR updates the WSLC CLI to prefer image remove over image delete, while preserving backward compatibility via aliases and adding a new top-level rmi entry point.

Changes:

• Renames the primary image deletion command from image delete to image remove, keeping delete/rm as aliases.
• Adds a new root-scoped rmi command for removing images.
• Updates E2E help-output expectations to reflect the new command naming and alias display.

LGTM. I recommend adding test coverage to validate that the aliases are wired (we could just check the help message for those specific commands here)

Good call, I think the test in this PR will fail after the new aliases show up. I will update them in the PR before completing it:
