Make the Logo link a normal page redirect

[emmenko]

Describe the issue

The Logo link currently does a client-side redirect, which eventually ends up in a full page redirect anyway.

merchant-center-application-kit/packages/application-shell/src/components/app-bar/app-bar.tsx

Lines 56 to 58 in 8537a38

	<Link to={`/${previousProjectKey || ''}`}>
	<img src={LogoSVG} width="100%" alt="Logo" />
	</Link>

To avoid possible unnecessary re-renders of the application, we can make it a normal page redirect in the first place.
