Fix S107 FPs: Don't count base constructor parameter in the threshold

[pavel-mikula-sonarsource]

As reported by @DAud-IcI here #1015 (comment):

When base class has parameter count close to the limit, the inheriting class adding few more parameters raises issue. We should substract the base class constructor parameter count from the treshold.

public class BaseService
{
    public string HttpContextAccessor { get; }
    public string LinkGenerator { get; }
    public string ServiceProvider { get; }
    public string MemoryCache { get; }
    public string Hca { get; }
    public string Settings { get; }

    public BaseService(string httpContextAccessor, string linkGenerator, string serviceProvider, string memoryCache, string hca, string settings)
    {
        HttpContextAccessor = httpContextAccessor;
        LinkGenerator = linkGenerator;
        ServiceProvider = serviceProvider;
        MemoryCache = memoryCache;
        Hca = hca;
        Settings = settings;
    }
}

public class DescendantService : BaseService
{
    private readonly string _stringLocalizer;
    private readonly string _logger;

    public DescendantService(string httpContextAccessor, string linkGenerator, string serviceProvider, string memoryCache, string hca, string settings,
        string stringLocalizer,
        string logger) // <-- S107 triggers on this constructor.
        : base(httpContextAccessor, linkGenerator, serviceProvider, memoryCache, hca, settings)
    {
        _stringLocalizer = stringLocalizer;
        _logger = logger;
    }
}
