Problem with [EnumMember] when using JsonStringEnumConverter #645
Description
The JsonStringEnumConverter does not and will not support [EnumMember] attributes. So when you use the JsonStringEnumConverter globally in your project, the enum's in fido2-net-lib's models can not correctly be serialized/deserialized. This is not a problem when using Newtonsoft.Json, but are hitting this issue because we are converting projects from Newtonsoft.Json to only use System.Text.Json.
To support this use case, in .NET 9 Microsoft has introduced the [JsonStringEnumMemberName] attribute.
When fido2-net-lib supports .NET 9 or higher, I would like to propose to add the [JsonStringEnumMemberName] to all properties currently decorated with the [EnumMember] attribute, so that serialization/deserialization with the JsonStringEnumConverter works out of the box.
This problem was also mentioned in #594
Thank you for your efforts in building and maintaining this library. If necessary I can create a PR when the library has been updated to use .NET 9 or higher.
