InfluxDB 2.0: The "/sources/{sourceID}/buckets" response type is defined as "Buckets" but returns a list of "Bucket" [area/api]

[bednar]

The /sources/{sourceID}/buckets response type is defined as Buckets:

/sources/{sourceID}/buckets:
    get:
      tags:
        - Sources
        - Buckets
      summary: Get a sources buckets (will return dbrps in the form of buckets if it is a v1 source)
      parameters:
          - $ref: '#/components/parameters/TraceSpan'
          - in: path
            name: sourceID
            schema:
              type: string
            required: true
            description: ID of the source
          - in: query
            name: org
            description: specifies the organization of the resource
            required: true
            schema:
              type: string
      responses:
        '200':
          description: a source
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Buckets"
        '404':
          description: source not found
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Error"
        default:
          description: unexpected error
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Error"

but HTTP response returns an array of Bucket:

-> GET 
-> http://127.0.0.1:9999/api/v2/sources/039042392f62d000/buckets

<- 200 
<- OK
<- [{
	"name": "telegraf",
	"rp": "autogen",
	"retentionPeriod": 0
}, {
	"name": "_internal",
	"rp": "monitor",
	"retentionPeriod": 604800000000000
}]
