Automatic Pulling of New Tags in Azure Container Registry Artifact Cache

**What is the problem you're trying to solve**
Currently, Azure Container Registry's artifact cache does not automatically pull new tags of images when they become available. This limitation affects the ability to automatically update Docker images with tools like Renovate, which requires the latest tag list to function properly.

**Describe the solution you'd like**
I would like Azure Container Registry's artifact cache to automatically pull new tags of images as soon as they are available. This would ensure that tools like Renovate can always access the most up-to-date tag list, enabling automated Docker image updates.

**Additional context**
The current documentation states:

_Cache only occurs after at least one image pull is complete on the available container image. For every new image available, a new image pull must be complete. Currently, artifact cache doesn't automatically pull new tags of images when a new tag is available._

This feature would improve the efficiency and usability of the artifact cache, especially for automated processes. Could you please let me know if this feature is planned for future releases? If so, when can we expect it to be available on the roadmap?
