[Bug] Fix a missing git config section

  * This will fix the following error:

```
  stderr: 'Author identity unknown

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.
```
