Remove paginatedVersion from GraphQL API

[adriangmweb]

Description

When introducing the paginated read models, there is a boolean property called paginatedVersion that tells whether the query is using the paginated version or not, to allow retro-compatibility. This should be removed in the future alongside the old read model version, so the paginated one is the standard.

Environment

• Booster version: [e.g. 0.17.0]
