Enhance REST API documentation for querying on nested objects

[LucasZapico]

Scope & Context

Description: The current OpenAPI spec does not call out the preferred method for filtering by nested object properties.

Proposed Change:

• Add abstract for to filter on nested object properties
• Add example for filter on nested object properties

Affected Files:

• parameters.utils.spec.ts
• parameters.utils.ts

Additional Context: This change will help improve the developer experience (DX) for users who are setting up integrations and services with the RestAPI.
