Added: Google Analytics Configurator

[Bram1903]

As requested in #451, users now have the ability to configure whether they want to use Google Analytics or not. By default, Google Analytics is disabled, and users can enable it through the appsettings.json.

The PrivacySettings class has been modified to support this feature with the following properties:

• UseGoogleAnalytics: A boolean that indicates whether Google Analytics should be enabled (true) or not (false).
• GoogleAnalyticsKey: A nullable string that holds the Google Analytics key when UseGoogleAnalytics is set to true. When Google Analytics is disabled, this property can be empty.

These changes allow users to have better control over Google Analytics integration, ensuring their privacy preferences are respected.

Updated configuration section:

"PrivacySettings": {
    "LogClientIpAddresses": true,
    "LogClientAgents": true,
    "UseGoogleAnalytics": false,
    "GoogleAnalyticsKey": ""
  },

Updated PrivacySettings class:

/// <summary>
///     Represents the privacy settings for the application.
/// </summary>
public class PrivacySettings
{
    /// <summary>
    ///     Gets the unique key to identify the PrivacySettings configuration.
    /// </summary>
    public const string Key = nameof(PrivacySettings);

    /// <summary>
    ///     Gets or sets a value indicating whether the client IP addresses should be logged.
    /// </summary>
    public bool LogClientIpAddresses { get; set; } = true;

    /// <summary>
    ///     Gets or sets a value indicating whether the client agents (user agents) should be logged.
    /// </summary>
    public bool LogClientAgents { get; set; } = true;

    /// <summary>
    ///     Gets or sets a value indicating whether Google Analytics should be used for tracking.
    /// </summary>
    public bool UseGoogleAnalytics { get; set; }

    /// <summary>
    ///     Gets or sets the Google Analytics tracking key.
    /// </summary>
    /// <remarks>
    ///     If <see cref="UseGoogleAnalytics" /> is set to true, this property must contain a valid Google Analytics tracking
    ///     key.
    /// </remarks>
    public string? GoogleAnalyticsKey { get; set; }
}

@neozhu, let's wait for the checks to finish before we merge the code.

I updated the CleanArchitecture.Blazor.nuspec just now as well. Can you quickly check if everything is alright before we merge this pull request?
