Breaking changes ⚠️

Semantic data provider

The httpClient is not exported anymore from the @semapps/semantic-data-provider package.
It must not be added to the dataProvider setting.

Auth provider

The httpClient and middlewareUri setting should be replaced with the dataProvider.
The middlewareUri is automatically calculated from the dataServers config (= the server with authServer: true)

Before:

import { authProvider } from '@semapps/auth-provider';
import { httpClient } from '@semapps/semantic-data-provider';
export default authProvider({
  middlewareUri: 'http://localhost:3000',
  httpClient
});

After:

import { authProvider } from '@semapps/auth-provider';
import dataProvider from "./dataProvider";
export default authProvider({
  dataProvider
});

Proxy service

The ProxyService is now exported from the @semapps/signature package instead of @semapps/activitypub.
