[feature]: Support of YamlDotNet 16

[mmgerald]

Is your feature request related to a problem? Please describe.

YamlDotnet looks like they have made some breaking changes in the latest release: https://github.com/aaubry/YamlDotNet/releases/tag/v16.0.0 specifically to ReadYaml and WriteYaml in IYamlTypeConverter.cs leaving any descendant in the KubernetesClient library broken (i.e., IntOrStringYamlConverter).

(see also kubernetes-client/csharp#1573)

Describe the solution you would like

Update KubernetesClient to recent version. I've already asked for a new release that includes dependency to v16 of YamlDotNet

Additional Context
