Springdoc not producing correct OpenAPI specification for an Iterable of enums in Scala

[nils1k]

Describe the bug

When I have a field of type Iterable of an enum, e.g. a Set or a Seq, then springdoc is not generating the correct OpenAPI specification.

To Reproduce
Steps to reproduce the behavior:

What version of spring-boot you are using?
Version 3.2.5.

What modules and versions of springdoc-openapi are you using?
Version 2.5.0 and the org.springdoc:springdoc-openapi-starter-webmvc-ui module.

What is the actual and the expected result using OpenAPI Description (yml or json)?
Expected result:

"fareClasses": {
    "type": "array",
    "description": "FareClasses",
    "items": {
        "type": "string"
    }
}

Actual result:

"fareClasses": {
    "type": "array",
    "description": "FareClasses",
    "items": {
        "type": "string",
        "enum": [
            "FIRST_CLASS",
            "SECOND_CLASS",
            "THIRD_CLASS",
            "ECONOMY_CLASS"
        ]
    }
}

Please refer to the sample code that reproduces the issue.

Expected behavior

The fareClasses field should be an enum.
