The current extension prototype assumes schema paths defined in the consumers extension.json are relative to the extensions directory rather than the extension root directory. This task is to re-work the current SchemaResolver logic an allow to define schemas relative to the consumer extension directory. For instance, current schema defined as `MyExtension/src/Schemas/schema.json` should be defined and loaded as `src/Schemas/schema.json`.
CommunityConfigurationExample has an example of this path definition that can be used for testing, see [[ https://gitlab.wikimedia.org/repos/growth/community-configuration-example/-/blob/main/extension.json?ref_type=heads#L26 | source ]].
**Acceptance criteria**
- [] Schema path definition for CC consumers is relative to the extension directory
- [] CommunityConfigurationExample is updated accordingly
