Image tag names with registry port are not split correctly

[detjensrobert]

In the images list and image detail view, the repo/tag parsing gets confused when an image tag registry has a port, and splits on the hostname:port colon instead of at the tag.

Reproduction steps

podman pull alpine:latest
podman tag alpine:latest localhost:5000/alpine:latest

Current behaviour behind, expected in front.

Environment

• Pods version: 2.1.2 (from Flathub)
• Fedora Kinoite
• Podman 5.3.1 (rootless)

I can make a PR to fix this if you'd like, made a patch to get the screenshot :)
