🎩 What? Why?

This PR:

• Defines a service to generate content blocks for landing pages of organizations, processes, assemblies or groups of processes
• Uses the service in the create_default_content_blocks command called in the organization creation
• Uses the service in the creation commands of processes, assemblies or groups of processes
• Defines a task to create default content blocks on existing processes, assemblies and groups of processes and optionally create content blocks associated to published components (this option only applies to processes and assemblies). The task can be called for a specific type of space using its space or resource manifest name (participatory_processes, assemblies or participatory_process_group) and also the id of an instance of their models can be specified
• Fixes a bug on extra_data participatory process group content block that occurs when the associated data is empty

NOTE

This PR depends on #10931 which implements association between participatory process group and content blocks via resource manifest. Once merged this PR the failing tests should pass
