[resources] inaccurate description for query parameters $top

[msyyc]

azure-rest-api-specs/specification/resources/resource-manager/Microsoft.Resources/stable/2021-04-01/resources.json

Lines 2955 to 2960 in b9f7b5b

	"name": "$top",
	"in": "query",
	"required": false,
	"type": "integer",
	"format": "int32",
	"description": "The number of results to return. If null is passed, returns all resources."

The description shows that it will return limited result if top is set. But actually, the call is pageable and service server will return limited result for every page, not that the final result is limited. So the description shall be like:

azure-rest-api-specs/specification/advisor/resource-manager/Microsoft.Advisor/stable/2017-04-19/advisor.json

Lines 354 to 358 in b9f7b5b

	"name": "$top",
	"in": "query",
	"description": "The number of recommendations per page if a paged version of this API is being used.",
	"required": false,
	"type": "integer"
