Description

In the JsonConverter.Write method for enums, there is only this line:

writer.WriteStringValue(counterEnum.ToString());

This causes enums to be written to JSON as "DailyMaintenance" or "MonthlyRinse" instead of "daily_maintenance" and "monthly_rinse" as they may be formatted in the OpenAPI specification.

Steps to reproduce

Define an enum in the specification which has values like "daily_maintenance" and "monthly_rinse"

None that I could find.

Suggest a fix

It seems like we should replace .ToString with BlahEnumValueConverter.ToJsonValue(blahEnum). I can open a PR for review.
