No longer usable in projects with C++/CLI

Due to a bug in RestSharp since Version 111.3, every version of Influxdb-client-csharp after the change from July 23, 2024, can no longer be used in a project that has to include a C++/CLI part as well.
https://github.com/RestSharp/restsharp/issues/2233
Maybe it is finally an issue large enough to move away from RestSharp.

__Steps to reproduce:__
List the minimal actions needed to reproduce the behavior.

1. Have an older project with C++/CLI, using InfluxDb-Client-CSharp 4.16.0 or older
2. Upgrade to current InfluxDb-Client-CSharp and try to compile

__Expected behavior:__
Compile without error

__Actual behavior:__
Compiling results in unresolvable error:
error C2870: 'RestSharp': a namespace definition must appear either at file scope or immediately within another namespace definition (compiling source file 'Stdafx.cpp')

__Specifications:__
- Client Version: 4.18.0
- InfluxDB Version: Irrelevant
- Platform: Windows 10@64, Windows11@64

Start by reproducing the compilation failure in the C++/CLI project described in the issue, using InfluxDB Client C# 4.18.0 and the RestSharp issue 2233 for context. Inspect the dependency and the reported Stdafx.cpp compilation path; done means the project compiles successfully on the specified Windows environments without the RestSharp namespace error.
