Support Bean Validation on records with Optionals

[lpandzic]

Given the controller:

import jakarta.validation.constraints.NotNull;
import jakarta.validation.constraints.Size;
import lombok.Value;
import org.springframework.web.bind.annotation.*;

import java.util.Optional;

@RestController
public class FooController {

    @PostMapping("fooRecord")
    public void fooRecord(@RequestBody FooRecord foo) {

    }

    @PostMapping("fooClass")
    public void fooClass(@RequestBody FooClass foo) {

    }

    record FooRecord(@NotNull Optional<@Size(max = 1000) String> value) {

    }

    @Value
    static class FooClass {
        @NotNull
        @Size(max = 1000)
        String value;

        public Optional<String> getValue() {
            return Optional.of(value);
        }
    }
}

currently with latest springdoc generated openapi looks like:

      "FooRecord":{
        "required":[
          "value"
        ],
        "type":"object",
        "properties":{
          "value":{
            "type":"string"
          }
        }
      },
      "FooClass":{
        "required":[
          "value"
        ],
        "type":"object",
        "properties":{
          "value":{
            "maxLength":1000,
            "minLength":0,
            "type":"string"
          }
        }
      },

under components schemas.
The problematic part is the FooRecord component.

The result I'd expect in ideal case would be

      "FooRecord":{
        "type":"object",
        "properties":{
          "value":{
            "maxLength":1000,
            "minLength":0,
            "type":"string"
          }
        }
      },
