Document standard $top/$skip parameters for ARM subscription list operations

[Copilot]

ARM docs described the reusable pagination parameter models, but did not show how to apply them to ArmListBySubscription via the Parameters template argument. This left a common authoring path undocumented and encouraged hand-rolled query models.

• What changed

  • Added focused guidance to the ARM resource operations how-to for subscription-scoped list operations.
  • Documented the canonical pattern for wiring standard pagination parameters through Parameters instead of defining raw @query("$top") / @query("$skip") properties.

• Documented parameter options

  • ARM-native reusable parameters:
    • ArmTopParameter & ArmSkipParameter
  • Azure Core reusable list model:
    • Azure.Core.StandardListQueryParameters

• Example

  @armResourceOperations
  interface Employees {
    listBySubscription is ArmListBySubscription<
      Employee,
      Parameters = ArmTopParameter & ArmSkipParameter
    >;
  }

  @armResourceOperations
  interface Employees {
    listBySubscription is ArmListBySubscription<
      Employee,
      Parameters = Azure.Core.StandardListQueryParameters
    >;
  }
