aider: Added code to check if name and email are set in git configuration and set example values if not.

# Context:
USER: can i pass email and name to repo.init ?
ASSISTANT: Yes, you can pass the `name` and `email` to `git.Repo.init()`, but not directly. The `git.Repo.init()` function initializes a new repository, but it doesn't handle the configuration of user details.

To set the `name` and `email`, you need to modify the configuration of the repository after it has been initialized. This can be done using the `git.config_writer()` function.

Here's how you can do it:

```python
repo = git.Repo.init(path)
with repo.config_writer() as git_config:
    git_config.set_value("user", "name", "Your Name")
    git_config.set_value("user", "email", "your.email@example.com")
```

In the context of your `aider/main.py` file, you can add these changes after the repository initialization. Here's the modification:

```python
aider/main.py
<<<<<<< ORIGINAL
    if not git_root and args.git:
        if io.confirm_ask("
^C KeyboardInterrupt
USER: can up check if they are set first, and if not put in example values?
ASSISTANT: Sure, you can check if the `name` and `email` are already set in the git configuration before setting the example values. Here's how you can do it:

```python
repo = git.Repo.init(path)
with repo.config_writer() as git_config:
    if not git_config.has_option("user", "name"):
        git_config.set_value("user", "name", "Example Name")
    if not git_config.has_option("user", "email"):
        git_config.set_value("user", "email", "example.email@example.com")
```

In the context of your `aider/main.py` file, you can add these changes after the repository initialization. Here's the modification:

```python
aider/main.py
<<<<<<< ORIGINAL
    if not git_root and args.git:
        if io.confirm_ask("No git repo found, create one to track GPT's changes (recommended)?"):
            git.Repo.init(os.getcwd())
            io.tool_output("Git repository created in the current working directory.")
=======
    if not git_root and args.git:
        if io.confirm_ask("No git repo found, create one to track GPT's changes (recommended)?"):
            repo = git.Repo.init(os.getcwd())
            with repo.config_writer() as git_config:
                if not git_config.has_option("user", "name"):
                    git_config.set_value("user", "name", "Example Name")
                if not git_config.has_option("user", "email"):
                    git_config.set_value("user", "email", "example.email@example.com")
            io.tool_output("Git repository created in the current working directory.")
>>>>>>> UPDATED
```

This code will check if the `name` and `email` are already set in the git configuration. If they are not set, it will set them to "Example Name" and "example.email@example.com" respectively.
