feat: add non-generic Deserialize method with dynamic code requirements to KubernetesJson

[kimpenhaus]

this PR adds a non-generic Deserialise method to KubernetesJson.cs

Reason:

based on this discussion adding a non generic Deserialize method gives the opportunity to use the same json serialisation mechanism everywhere - when using KubernetesClient package.

Pull request overview

This PR adds a non-generic Deserialize(string json, Type returnType, JsonSerializerOptions jsonSerializerOptions = null) method to the KubernetesJson class. This provides an alternative to the existing generic Deserialize<TValue> methods when the target type is only known at runtime, enabling more flexible use of the Kubernetes client's JSON serialization infrastructure.

Key changes:

• Adds a new public non-generic Deserialize method that accepts a Type parameter
• Includes appropriate RequiresDynamicCode and RequiresUnreferencedCode attributes for .NET 8.0+ to warn about AOT compatibility concerns
• Imports System.Diagnostics.CodeAnalysis namespace for the new attributes

what about

        var elm = KubernetesJson.Deserialize<JsonElement>(json);
        var result = elm.Deserialize(typeof(V1Secret));

i felt uncomfortable about the warning in sdk

[kimpenhaus]

@tg123 thanks for the feedback - the warning mentioned by CoPilot is outdated - I've changed the code and there is no warning anymore. It's proper implemented now acording to the different sdk versions.

One can go with the step to JsonElement for sure - but I think this feels more unnatural to general dotnet api. there used to be a generic and a non generic variant.
