feat: Handle includePreTranslatedStringsOnly parameter for AddTaskRequest

[Riju-bak]

Related issue: https://github.com/crowdin/crowdin-api-client-dotnet/issues/163

Description: Crowdin-API's Add Task API now requires an includePreTranslatedStringsOnly parameter. crowdin-api-client-dotnet should thus be able to handle requests that contain this parameter within the body.
