Ink 4.4.x incorrectly detects backspace

[cpendery]

On Windows, backspace is properly detected; however, on Linux backspace is detected as delete

Minimal reproducible example

import React from 'react';
import {render, useInput, Text} from 'ink';

function Input() {
	useInput((_, key) => {
		if (key.backspace) {
			console.log("backspace")
		}
		else if (key.delete) {
			console.log("delete")
		}
	});

	return (
		<Text>Example</Text>
	);
}

render(<Input />);
