Enum string with special character not quoted in yaml

[StefanSrf]

Expected Behavior

Enum-strings with special characters should be quoted in yaml.

Example:

enum class DemoEnum {
    @JsonProperty("escaping-dash")
    ESCAPING_DASH,
    @JsonProperty("noEscaping")
    NO_ESCAPING
}

should result in

    DemoEnum:
      type: string
      enum:
      - 'escaping-dash'
      - noEscaping

Actual Behaviour

Invalid string in yaml, e.g. escaping-dash instead of 'escaping-dash'

    DemoEnum:
      type: string
      enum:
      - escaping-dash
      - noEscaping

@StefanSrf don't need to escape it. This is normal yaml file. You can check it on https://editor.swagger.io
