Need to provide the `jobs/{jobId}/outputs/{outputId}/{N}` definitions

The endpoint jobs/{jobId}/outputs/{outputId}/{N} is defined in OpenAPI schema: https://github.com/opengeospatial/ogcapi-processes/blob/master/openapi/paths/processes-core/pResultOutputValue.yaml

However, the requirements are not provided.
The above reference mentions

For more information, see Section 7.14.

However, this is not correct. The sc_retrieve_job_results_one pointer refers to the following endpoint, which is about retrieving "one output" (as in "only 1 {outputID} requested", not N=1 item within a given multi-value/array {outputID} result).

https://github.com/opengeospatial/ogcapi-processes/blob/4a4a1dce7b919f969b681cf96186e85ed3f5da1f/core/sections/clause_7_core.adoc?plain=1#L1423-L1426

https://github.com/opengeospatial/ogcapi-processes/blob/4a4a1dce7b919f969b681cf96186e85ed3f5da1f/core/requirements/core/REQ_job-results-success-async-one.adoc?plain=1#L1-L29

This distinction also highlights that mention like "The number of requested outputs is 1. or "N requested outputs" can be easily misinterpreted with that N array parameter (as described in https://github.com/opengeospatial/ogcapi-processes/issues/580#issuecomment-4314034921).

One or multiple dedicated /req/... definitions must be provided to clarify that distinction, and also to include it in the AST since it needs a dedicated (or additional part) operation to actually test the index-based access.
