[BUG] Fix committing all files when creating a new template

[drewstone]

Overview

When creating a new blueprint template from the CLI. If you run git add . it immediately commits all the files within the submodules. The submodules are thus not being committed as submodules and instead create an extra step for us when beginning to build blueprints.

Steps to reproduce

1. cargo tangle blueprint create --name <...>
2. cd <...>
3. git add .
