pa.get_info() fails with PyAudacityException: format argument must be one of "JSON", "LISP", or "Brief"

```python
import pyaudacity as pa
pa.get_info()
```
fails with `PyAudacityException: format argument must be one of "JSON", "LISP", or "Brief"`.

Reason: The `format`-parameter is initialized with `"JSON"` and [subsequently `title()`-fied](https://github.com/asweigart/pyaudacity/blob/main/src/pyaudacity/__init__.py#L3730) which turns it into `"Json"`, which makes it impossible to pass anything for the `format`-parameter but `"Brief"`.

Fix: remove [call](https://github.com/asweigart/pyaudacity/blob/main/src/pyaudacity/__init__.py#L3730) to `title()` on parameter `format`.

Open src/pyaudacity/__init__.py around line 3730 and inspect how get_info() normalizes its format parameter. Run the reported pa.get_info() snippet before and after the change, then verify that the default call succeeds and the documented JSON, LISP, and Brief formats remain accepted.
