Update Target Frameworks

[Uight]

Currently in the target frameworks of the project the following are listed: netstandard2.0;net461;net5.0;net6.0

i would consider changing it a bit for the following reasons: net461 is out of support since beginning of 2022 therefor atleast use net462 which is still officialy supported. net5.0 is out of support; net6.0 runs out of support this year but is okay for now; netstandard2.0 is kind of tricky but as its currently supported you would probably keep supporting it.

net framework support: https://learn.microsoft.com/de-de/lifecycle/products/microsoft-net-framework .net support: https://dotnet.microsoft.com/en-us/platform/support/policy .net standard infos: https://learn.microsoft.com/en-us/dotnet/standard https://learn.microsoft.com/en-us/dotnet/standard/net-standard?tabs=net-standard-1-0#net-5-and-net-standard

I would like to change supported frameworks to: netstandard2.0;net462;net6.0;net8.0
