[BUG] kotlin-spring generator, different results for enum classes and in-place enums (mustache templates)

Hi,
I noticed following difference in the generated enum, when using an enum class over an in-place enum in a data class. The difference is already in the mustache Templates:

• Data Class
  @JSONProperty is set, so the enum is generated using the value given in the @JSONProperty. Here it is the enum value from the Open Api Spec. See the description for x-enum-varnames
• Enum Class
  @JSONProperty is not set, so the enum is generated using the enum name

This leads to different behavior in the handling of enums inside the spring application. I fixed it by overwriting the
mustache Template enumClass.mustache as follows:

import com.fasterxml.jackson.annotation.JsonProperty

/**
* {{{description}}}
* Values: {{#allowableValues}}{{#enumVars}}{{&name}}{{^-last}},{{/-last}}{{/enumVars}}{{/allowableValues}}
*/

enum class {{classname}}(val value: {{dataType}}) {
{{#allowableValues}}{{#enumVars}}
    @JsonProperty({{{value}}}) {{&name}}({{{value}}}){{^-last}},{{/-last}}{{#-last}};{{/-last}}
{{/enumVars}}{{/allowableValues}}
}

hope it helps
Kind regards
Jonny

Compare the Kotlin Spring templates at modules/openapi-generator/src/main/resources/kotlin-spring/dataClass.mustache and enumClass.mustache, starting with their JsonProperty annotations and enumVars handling. Regenerate equivalent enum-class and in-place-enum schemas, then verify both forms use the OpenAPI enum values consistently in the generated Kotlin code.
