Build CI Catalog index page
## Description
This is the epic for the index page of the Catalog. We are going to focus on creating the scaffolding of the index page for a private catalog, the list of components that it shows and the ability to search and filter content.
This also includes things like pagination, setting up the Vue Router, feature specs, QA specs (as required), etc.
