SyntaxError: unterminated string literal when using \n in string with pyodide.runPython()

## 🐛 Bug

When using `pyodide.runPython()` with a string containing a `\n` newline character inside a Python string literal, a `SyntaxError: unterminated string literal` is thrown, even though the string is properly terminated.

### To Reproduce

```html

async function main(){
let pyodide = await loadPyodide();
pyodide.runPython("print('hello\nworld')");
}
main();

```

### Expected behavior

The code should execute without errors and print:
```
hello
world
```

### Environment

- Pyodide Version: 0.29.0
- Browser version: 135.0.7049.72
- Any other relevant information: The error occurs when a newline escape sequence (`\n`) is included inside a single-quoted Python string passed to `runPython()`.

### Additional context

The error message indicates that the Python parser detects an unterminated string literal at the line containing `print('hello`, suggesting that the `\n` escape sequence is being interpreted as a literal newline in the Python source code rather than a string escape, causing the string to be split across lines and appear unterminated.
