Casing in generated code is wrong

**Describe the bug** For some methods I get since version 2.0.0 the following issue: 'Generated.ProcessEngineApiIProcessEngineApiv1' does not implement interface member 'IProcessEngineApiv1.FormGet(string, string, CancellationToken)' Because the generated Code looks like that: ```csharp         public async global::System.Threading.Tasks.Task<global::Refit.IApiResponse<global::ProcessEngineApi.Contracts.Form>> FormGET(string @elementInstance, string @elementType, global::System.Threading.CancellationToken @cancellationToken) ``` Notice that the name in the generated interface is `FormGet` but in the class it is `FormGET`.
