Use constructor property promotion and type declarations

Problem/Motivation

New modules, which are compatible with Drupal 10 and higher versions are expected to include type declarations in property definitions, and use constructor property promotion.

  /**
   * Get the migration plugin manager.
   *
   * @var \Drupal\migrate\Plugin\MigrationPluginManagerInterface|object|null
   */
  protected MigrationPluginManagerInterface $migrationPluginManager;

  /**
   * {@inheritdoc}
   */
  public function __construct(MigrationInterface $migration, MigrateMessageInterface $message, array $options = []) {

  /**
   * Plugin manager for migration plugins.
   */
  protected MigrationPluginManagerInterface $migrationPluginManager;

  /**
   * The logger service.
   *
   * @var \Psr\Log\LoggerInterface
   */
  protected LoggerInterface $logger;

  /**
   * The http client.
   *
   * @var \GuzzleHttp\Client
   */
  protected Client $httpClient;

  /**
   * Constructs a new MigrationExecuteForm object.
   *
   * @param \Drupal\migrate\Plugin\MigrationPluginManagerInterface $migration_plugin_manager
   *   The plugin manager for config entity-based migrations.
   * @param \Psr\Log\LoggerInterface $logger
   *   The logger service.
   * @param \GuzzleHttp\ClientInterface $http_client
   *   The Guzzle HTTP client.
   */
  public function __construct(
    MigrationPluginManagerInterface $migration_plugin_manager,
    LoggerInterface $logger,
    Client $http_client,
  ) {
    $this->migrationPluginManager = $migration_plugin_manager;
    $this->logger = $logger;
    $this->httpClient = $http_client;
  }

Proposed resolution

Review and update the module code to comply with Drupal 10+ standards.
