[Bug]: Another `##default` leaks case (version 2.2.44 and 2.2.45): `@Parameter` + `@ArraySchema`

[zqq90]

Description of the problem/issue

##default leaks to parameters if annotated with @Parameter(array = @ArraySchema(...))

Affected Version

2.2.45

Earliest version the bug appears in (if known):
2.2.44

Steps to Reproduce

@GetMapping("/tests/default-leaks")
public IResponse<Void> testDefaultLeaks(
        DefaultLeaksParams params,
        @Parameter(
                array = @ArraySchema(minItems = 1)
        )
        List<String> directLeaks
) {
    return ok();
}

@org.springdoc.core.annotations.ParameterObject
public record DefaultLeaksParams(
        @Parameter(
                array = @ArraySchema(schema = @Schema(type = "string"))
        )
        List<String> leaks1,
        @Parameter(
                array = @ArraySchema(minItems = 1)
        )
        List<String> leaks2,
        @Parameter
        List<String> doesNotLeaks
) {
}

Expected Behavior

"##default" should not leaks to schema

Actual Behavior

"parameters": [
  {
      "name": "leaks1",
      "in": "query",
      "required": false,
      "schema": {
          "type": "array",
          "default": "##default",
          "items": {
              "type": "string"
          }
      }
  },
  {
      "name": "leaks2",
      "in": "query",
      "required": false,
      "schema": {
          "type": "array",
          "default": "##default",
          "minItems": 1
      }
  },
  {
      "name": "doesNotLeaks",
      "in": "query",
      "required": false,
      "schema": {
          "type": "array",
          "items": {
              "type": "string"
          }
      }
  },
  {
      "name": "directLeaks",
      "in": "query",
      "required": true,
      "schema": {
          "type": "array",
          "default": "##default",
          "minItems": 1
      }
  }
]

Springdoc uses swagger-core 2.2.43, and has thus not adjusted for the breaking change that was introduced by defining ##default as the new default's default.

So most likely the change needed is within springdoc so that its parameter processing has to account for ##default rather than "" when it looks for an empty default value.

The issue seems to be this code in springdoc.
