How do I export a C# function with a `JSValue` argument?

As per issue title, I'm trying to export a C# class method using TypeExporter.ExportType, but the method is not exported due to the following check, which explicitly disallows JSValue argument types and causes the method to be skipped:

https://github.com/microsoft/node-api-dotnet/blob/a150c53280dbbdebbc51cb84d7384fa3f9313e4b/src/NodeApi.DotNetHost/TypeExporter.cs#L1026-L1028

The method has the following signature:

public async Task<JSValue> sendMessage(JSValue parameters)

The purpose of the C# function is:

• to call JSON.stringify
• parse the result with System.Text.Json
• execute some C# code,
• serialize the result with System.Text.Json
• call JSON.parse again to return the result to nodeJS.

(I know, the JSON round-trip could be removed in the future by creating a DTO type, but the JSON data currently has a dynamic structure and needs some work)

Changing the signature to a string and using JSON.stringify in NodeJs is a workaround to make the method appear, but I'd like to pass a JSON object directly.
