fix: git config system (#390)

Changing the Make target Docker command to mimic the GitHub Actions environment
to cause the same failure.

* https://git-scm.com/docs/git-config#Documentation/git-config.txt---global

```
--global
For writing options: write to global ~/.gitconfig file rather than the repository .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the ~/.gitconfig file doesn’t.

For reading options: read only from global ~/.gitconfig and from $XDG_CONFIG_HOME/git/config rather than from all available files.
```

* https://git-scm.com/docs/git-config#Documentation/git-config.txt---system

```
For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository .git/config.

For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than from all available files.
