remove commented code on module

Problem/Motivation

I observed many area commented code this there we need to cleanup.

  public function build() {
    $menu_name = $this->getDerivativeId();
    $parameters = new MenuTreeParameters();

    // Adjust the menu tree parameters based on the block's configuration.
    // $level = $this->configuration['level'];.
    $depth = $this->configuration['depth'];
    // $parameters->setMinDepth($level);

Steps to reproduce

need to check the path
src/Plugin/Block/FullMenuBlock.php

Proposed resolution

Remaining tasks

User interface changes

API changes

Data model changes
