Add icons in project list to indicate the container and package registries are in use
### Problem to solve
It's difficult at a glance to identify projects / groups that include container images or packages. When searching for projects with either of these, you have to _know_ which projects contain them or manually check by entering the project and navigating to either the container or package registry.
### Intended users
* [Sasha (Software Developer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sasha-software-developer)
* [Devon (DevOps Engineer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#devon-devops-engineer)
* [Sidney (Systems Administrator)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sidney-systems-administrator)
### Proposal
We could extend the project icons to include new icons for:
* Showing that the container registry is enabled and has at least one image (I don't think we can show a total count?)
* Showing that the package registry is enabled with a total of `n` packages
These icons could be added here:
