Cannot find symbol 'allowableValues' in pathParams template with oas3 and JavaSpring

Description

Defining an enum schema in parameters object will cause the following compiling error:

'cannot find symbol': allowableValues

You can see the causing code here:

https://github.com/OpenAPITools/openapi-generator/blob/5.3.x/modules/openapi-generator/src/main/resources/JavaSpring/pathParams.mustache

The field "allowableValues" no longer exists in the annotation @Parameter from io.swagger.v3.oas.annotations

openapi-generator version

5.3.1

OpenAPI declaration file content or url

openapi: 3.0.3

        - name: myEnum
          in: path
          required: true
          schema:
            $ref: '#/components/schemas/MyEnum'

      type: string

Generation Details

I am using the maven plugin with the following config option:

<oas3>true</oas3>

Steps to reproduce

generate with maven plugin

Suggest a fix

Remove "allowableValues" from the template and use the @Schema annotation

Start in modules/openapi-generator/src/main/resources/JavaSpring/pathParams.mustache and inspect how the enum path parameter is rendered for the oas3 option. Reproduce the issue with the provided OpenAPI declaration and Maven plugin configuration, then verify that generated JavaSpring code compiles without the missing allowableValues symbol.
