Repository.Init wants to write to workingDirectoryPath

Reproduction steps

Run the following code with workingDirectoryPath set to a write-protected directory path and gitDirectoryPath set to a writable directory path:

Lib2GitSharp.Repository.Init(workingDirectoryPath: "/", gitDirectoryPath: "/some/dir/.git")

Expected behavior

The Init() call works exactly as this git command: git --git-dir /some/dir/.git --work-tree /:

• it creates a .git repository directory at /some/dir/.git with its config's core.worktree set to /
• it does not touch the --work-tree directory / in any way and thus does not need write permissions in this directory

Actual behavior

An Exception of type Lib2GitException is thrown:
failed to initialize repository with template '.git': Permission denied

Comienza en el punto de entrada Repository.Init y reproduce el problema con un workingDirectoryPath protegido contra escritura y un gitDirectoryPath escribible. Se considera terminado cuando la inicialización crea el repositorio y establece core.worktree en el directorio de trabajo sin intentar escribir allí, siguiendo el comportamiento indicado del comando git.
