Add code clone component to repository page ⬇️

[JamieSlome]

Is your feature request related to a problem? Please describe.

Without pagination and search (until #606), it can be painful to locate the clone command/URL on the Repositories page.

Describe the solution you'd like

Create a component for the widget (<Clone />) and add component to the Repository page.

Additional context

The code to move into a new <Clone /> component can be found in RepoOverview.js from line 688 to 778.
