Add PropertyNameGenerator as an optional Parameter

[fsamiec]

Is your feature request related to a problem? Please describe.
Currently, CodeGeneratorSettings does not provide an option to define a custom PropertyNameGenerator. In my projects this does not match the PascalNaming convention, as the properties are named like this:

[System.Text.Json.Serialization.JsonPropertyName("business_partner")]
public int Business_partner { get; set; }

[System.Text.Json.Serialization.JsonPropertyName("main_consultant_number")]
public int Main_consultant_number { get; set; }

Describe the solution you'd like
I would like to see an option in CodeGeneratorSettings that allows for the integration of a custom PropertyNameGenerator like the given sample below:

//Refitter.Core/CSharpClientGeneratorFactory.cs
internal class CSharpClientGeneratorFactory(RefitGeneratorSettings settings, OpenApiDocument document)
{
	public CustomCSharpClientGenerator Create()
    {
		var csharpClientGeneratorSettings = new CSharpClientGeneratorSettings
		{
			CodeGeneratorSettings = { PropertyNameGenerator = settings.CodeGeneratorSettings.PropertyNameGenerator ?? new CustomCSharpPropertyNameGenerator(), },
		};
	}
}

//Refitter.Core/Settings/RefitGeneratorSettings.cs

/// <summary>
/// Provide settings for Refit generator.
/// </summary>
[ExcludeFromCodeCoverage]
public class RefitGeneratorSettings
{    
	/// <summary>Gets or sets the property name generator.</summary>
	[JsonIgnore]
	public IPropertyNameGenerator PropertyNameGenerator { get; set; }		
}

Describe alternatives you've considered
NSwag unfortunately does not meet our logging requirements, as we need the method names from the RestMethodInfo.

Additional context
If there is any other way to customize the property names please let me know.

@fsamiec Thanks for taking the time to report this. Unfortunately, I'm too busy with other things to look into this. If you find a solution yourself and create a pull request, then I will find the time to review and make sure your fix gets merged in and released. Otherwise, this will have to wait a few weeks
