Improve container registry UX

Description

Right now the container registry has some UX downsides, especially if you are a heavy container registry user. This proposal describes the first step for a better UX.

Proposal

• Add the ability to see the last updated event time on registry repositories (similar to docker hubs Last pushed). This is often an information you need on the first glance.

• Remove docker pull from registry clipboard text. Nowadays the local testing with docker pull <registry_image> is more or less outdated. Often you use docker-compose.yml's, equivalent kubernetes yml or Dockerfiles where you just need the image tag. So let's remove docker pull

• Sort the registry tag list by created at date. Sorting them by tag does not make much sense from user perspective. Which images are on first glance important? The newest one. Right now you need to go trough a bunch of pagination pages to may find your image you are searching for (eg. we have rolling minor version number tags + multiple tags per build). So lets show the newest created image always at first. From security point of view it is as well a benefit. Usually you always want to pull the newest image for security fixes, features etc.

Examples (the tags are just an example with no sense :D I just retagged some images for testing):

Right now:
