CLI screenshots for Run, Build and Share are placeholders

While looking into the CLI cards, I noticed that cli-run-image.png, cli-build-image.png, and cli-share-image.png are all using the same $ podman --help screenshot.

cli-find-image.png has the actual command-specific output, so I think the other three should have their respective podman run, podman build, and podman push screenshots as well.

The paths in data.ts look correct, so this seems to just be an issue with the image assets.

Inspect the CLI card references in data.ts and compare cli-find-image.png with cli-run-image.png, cli-build-image.png, and cli-share-image.png. Replace the three placeholder assets with command-specific screenshots for podman run, podman build, and podman push, then verify that each CLI card displays the intended image.
