Display available metadata for Composer

Context

The Package GraphQL API returns helpful details about a Composer package hosted in the GitLab Package Registry.

Problem to solve

The problem is that not all of the data returned via GraphQL is displayed in the user interface. This makes it harder to use the UI as the single source of truth for packages.

Proposal

Update the package registry user interface to display all of the available metadata for Composer packages.
