[Feature Request] Clone Template Repository

[emsesc]

Is your proposal related to a problem?

To create a student repository to begin the course, this needs to be done manually. Instead, there should be a solution implemented in the Github App to clone the template repository containing the course files automatically.

Dependent on #135

Describe the solution you'd like

A POST request will be made to the Github API from the Github App, and it will clone the specified template repository in the POST request to the authenticated user's account.

Github App --> Github API

Describe alternatives you've considered

None.

Additional context

camp.dev --> POST Request --> Github App HTTP route endpoint --> clone repository with POST request to Github API --> template repository created on student account
