Vitest: Fix default viewport

[kasperpeulen]

What I did

The default viewport in storybook is MINIMAL_VIEWPORTS.

storybook/code/addons/viewport/src/legacy/ToolLegacy.tsx

Lines 122 to 127 in 513bb66

	const {
	viewports = MINIMAL_VIEWPORTS,
	defaultOrientation,
	defaultViewport,
	disable,
	} = useParameter<ViewportAddonParameter>(PARAM_KEY, {});

The addon now also uses that as default.
