Google style docstring code block is not rendered correctly

Environment

• Pydoc-Markdown Version: 4.8.2
• Python Version: v3.10.11
• Operating System: macOS 13.4.1

Describe the bug

Using a Google-style code block retains its indentation and does not render correctly in markdown (VS Code and GitHub rendering).

Simple Python example (in src/module-test.py):

from typing import Union, Optional, Any

def str_test(
    in_str: Any,
    num: int
) -> str:
    """
    Prints something to the screen and adds 'something' to the end.

    Args:
        in_str (Any): any string
        num: Number of times to add 'something' at the end in order to test
            how this darn thing works

    Returns:
        str: String with 'something' added

    Raises:

    Example:

        How to use:

        ```python
        # A comment
        msg = str_test("Hello", 2)
        print(msg)
        ```

    """

    msg = str(in_str)
    for i in range(num):
        msg = f"{msg} something"
    return msg

if __name__ == "__main__":
    text = str_test("hello", 2)
    print(text)

Produce markdown with:

pydoc-markdown -I src/ '{renderer: {type: markdown, escape_html_in_docstring: false}}' > module-test.md

module-test.md has the following:

<a id="module-test"></a>

# module-test

<a id="module-test.str_test"></a>

#### str\_test

```python
def str_test(in_str: Any, num: int) -> str
```

Prints something to the screen and adds 'something' to the end.

**Arguments**:

- `in_str` _Any_ - any string
- `num` - Number of times to add 'something' at the end in order to test
  how this darn thing works
  

**Returns**:

- `str` - String with 'something' added
  

**Raises**:

  

**Example**:

  
  How to use:
  
    ```python
    # A comment
    msg = str_test("Hello", 2)
    print(msg)
    ```

The extra indentation on the code block renders the backticks as follows:

I've tried many different combinations of with/without backticks and indentations. It either renders as shown above or does not render the code block at all (treated as markdown text).

Any idea on how to format the Google-style docstring to make the code block render correctly?

Expected behavior

Google-style docstring with "Examples:" section should render correctly in markdown.
