docs: Table.to_csv documentation not updated

[luca-ferreri]

Please describe the issue

The Table.to_csv documentation appears outdated. It only mentions PyArrow-specific parameters, whereas practical usage suggests that the method accepts arguments depending on the backend in use.

Suggested Improvement:
The section could be enhanced to clarify this behavior, similar to the Table.to_json documentation, which explicitly states:

Additional, backend-specific keyword arguments.
