Update eclipsefdn projects widget to handle new releases format

We need to update the projects widget to support the new project response from the API https://projects.eclipse.org/api/projects and handle it as an additional request to get all the releases data if needed.

This arose an issue for eclipsefdn/it/websites/ecdtools.eclipse.org#269 (closed)
