 - Major release because of fundamental change in the way the module is
   expected to be used for registering pages.
-- global: remove `has_custom_view` model field 
-- views: allow passing Jinja context to `render_page` 
-- ext: remove finalize_app usage 
-  - The previous design of the module had some major usability issues:
-    - The assumption that we have views that are dynamically registered
-      without the need to redeploy/reload the application for code
-      changes is fundamentally flawed. In reality order for such views
-      to be accessible/discoverable, one has to be able to reference
-      them in Jinja templates, which in turn means one has to make code
-      changes.
-    - The way we were registering page views, required having a
-      connection to an already initialized database. This imposes having
-      to perform checks at application initialization that go against
-      well-established principles of the Flask/Invenio app lifecycle.
-- fix: before_app_first_request deprecation
