fix(openapi): remove duplicate cursor wrapping in pipelines and exporters responses (#1312)

V2ListPipelinesResponse and V2ListExportersResponse had a nested cursor structure
(cursor.cursor.data) instead of the expected flat one (cursor.data). The responses
wrapped the CursorResponse schema in an extra cursor property with a redundant allOf,
while the referenced schemas already contained the cursor structure.
