[Bug] Description for array schema is being ignored when generating OpenAPI 3.1

[jochenberger]

I have the following Java code:

class Street {
        @ArraySchema(schema = @Schema(implementation = House.class, description = "A house in the street"),
                     arraySchema = @Schema(description = "The houses in the street"))
        public List<House> houses;
}

When generating OpenAPI 3.0, I get

Street:
type: object
properties:
  houses:
    type: array
    description: The houses in the street
    items:
      $ref: "#/components/schemas/House"

The item description is missing, but that's another issue (#3900).
However, when I generate OpenAPI 3.1, I get

Street:
type: object
properties:
  houses:
    type: array
    items:
      $ref: "#/components/schemas/House"
      description: A house in the street

Now, the item description is there, but the array description is missing.

I have the same problem.

See issue where I described the problem:
springdoc/springdoc-openapi#2953

From OpenAPI 3.0:

...
  "components": {
    "schemas": {
          "ClassName": {
            "type": "object",
            "properties": {
              "fieldName1": {
                "type": "string",
                "description": "A text here1."
              },
              "fieldName2": {
                "type": "array",
                "description": "A text here2.",
                "items": {
                  "type": "string"
                }
              }
            }
          }
...

And in OpenAPI 3.1:

...
  "components": {
    "schemas": {
          "ClassName": {
            "type": "object",
            "properties": {
              "fieldName1": {
                "type": "string",
                "description": "A text here1."
              },
              "fieldName2": {
                "type": "array",
                "items": {
                  "type": "string"
                }
              }
            }
          }
...

Doesn't seem to be fixed in 2.2.31.

[jochenberger]

Sill missing in 2.2.34.

#4942 has a failing test but I haven't managed to come up with a fix yet.
