Problem Description: 

1. Tag an image locally
podman pull hello-world
podman tag hello-world localhost:5001/hello-world:mytag

2. Push image to HUB
podman push localhost:5001/hello-world:mytag --tls-verify=false

3. Go to execution environments and see that it shows `hello-world:latest` 

NOTE: when pulling it is possible to pull `:mytag` so it exists in the registry.

Expected Results:

UI shows the tag that was pushed `mytag`

Proposed Solution: UI must read the tags_list?

Reminders:

• Set the affected Component(s): Backend, Infrastructure, Pulp, QE, Security, UI
• Apply labels "crc-automation-hub" and/or "private-automation-hub" to indicate if the issue is for Cloud Automation Hub, Private Automation Hub, or both
