refactor(templates): use depth of 1 in clone command to limit history… (

#2488)

addresses #2487 

## Summary
Creating a project using one of the templates will clone the entire
history of the repo.
Only one commit is really needed in order to access the template files
used to initialize a project.
This change creates a shallow clone with a depth of 1 to reduce the
amount of history that is fetched which should increase speed without
sacrificing any functionality

## How was it tested?
1. `devbox run build`: build devbox
2. `time devbox create --template go test1`: time the devbox create
command and confirm it clones faster and still creates the project
