[Toggle] keyboard interactions don't dispatch change event

[theetrain]

Issue

e.preventDefault() is called during a keyup event:

carbon-components-svelte/src/Toggle/Toggle.svelte

Lines 67 to 72 in c1c8309

	on:keyup="{(e) => {
	if (e.key === ' ' || e.key === 'Enter') {
	e.preventDefault();
	toggled = !toggled;
	}
	}}"

This prevents the change event from dispatching that otherwise should. Is this intentional?

Reproduction

Demo: https://stackblitz.com/edit/sveltejs-kit-template-default-ewqjmk?file=src%2Froutes%2F%2Bpage.svelte (inspired by #1609)

• clicking on the toggle will call the on:change handler
• using the ENTER or SPACE keys will not call the on:change handler

Proposal

I think it would be fair to forward on:keydown without handling it. The HTML <input type="checkbox"> will fire change on click and SPACE, not ENTER.
