GenericParameterService#isExplodable method should recognise @ArraySchema as well

[coutin]

Describe the bug
It seems that sprindoc is not allowing the usage of explode attribute on Parameter, when it s combined with an ArraySchema annotation.

I ve been debugging the issue and spotted that GenericParameterService has a method isExplodable that only supports @Schema annotation, which is not enough in case of Array, because you can't define the items type in the Schema annotation.

To Reproduce
Steps to reproduce the behavior:

• What version of spring-boot you are using? 2.4.0
• What modules and versions of springdoc-openapi are you using? springdoc-openapi-ui 1.5.0

@GetMapping(value = "helloWorld")
@Operation(summary ="helloWorld", description = "helloWorld")
public List<String> helloWorld(
    @Parameter(description = "Dummy list", required = true, explode = Explode.FALSE, , array = @ArraySchema( schema = @Schema(type = "string")), style = ParameterStyle.FORM) @RequestParam(dummyList) List<String> dummyList) { 
   return dummyList; 
} 

Produce parameter like

          {
            "name": "dummyList",
            "in": "query",
            "description": "Dummy list",
            "required": true,
            "style": "form",
            "schema": {
               "type": "array",
               "items": {
                   "type": "string"
               }
            }
          }

Expected behavior
So basically it is expected that @ArraySchema should be treated as @Schema type array, to ensure that array in query parameters are correctly typed in the open api spec.

So it should produce a parameter like :

`Should produce a parameter like :

          {
            "name": "dummyList",
            "in": "query",
            "description": "Dummy list",
            "required": true,
            "style": "form",
            "explode": false,
            "schema": {
               "type": "array",
               "items": {
                   "type": "string"
               }
            }
          }
