Admin UI - Configurable Link Component

[adrians5j]

With this PR, we're trying to make @webiny/admin-ui package not be dependent on @webiny/app.

We do this by making the @webiny/admin-ui code not directly use the SimpleLink component. Instead, we let the user supply it via the new AdminUiProvider. For example (https://github.com/webiny/webiny-js/blob/5be8971f45f42acc7d74afae087ce909789e8775/packages/app-admin/src/base/providers/UiProviders.tsx):

import React from "react"; import { createProvider, SimpleLink } from "@webiny/app"; import { AdminUiProvider } from "@webiny/admin-ui"; interface UiProvidersProps { children: React.ReactNode; } export const createUiProviders = () => { return createProvider(Component => { return function UiProviders({ children }: UiProvidersProps) { return ( <AdminUiProvider linkComponent={SimpleLink}> <Component>{children}</Component> </AdminUiProvider> ); }; }); };

Note

If not supplied, @webiny/admin-ui has its own default implementation of the Link component (basic a tag).

With this change, @webiny/app package is no longer a dependency of @webiny/admin-ui.
