Fix the response format for `actions/workflows`. (#35009)

This PR fixes the response format for the OpenAPI Spec of
`ActionsListRepositoryWorkflows`.
It was specified in the OpenAPI spec as returning a `[]*ActionWorkflow`,
but it actually should return a `api.ActionWorkflowResponse`.

The test already expects an `api.ActionWorkflowResponse` like expected.
