Fix the PHP_CodeSniffer issues reported by GitLab CI

Above error/warnings fixed.

Patch #2 applied cleanly all errors and warnings are fixed.
So moving it to RTBC.
Thanks

+  /**
+   * Constructs a FileManagementViewController object.
+   */
+  public function __construct(EntityTypeManagerInterface $entity_type_manager) {

The class name is missing its namespace.

+  /**
+   * The File Management service.
+   *

File and Management are misspelled.

     $link = Link::fromTextAndUrl(
       $file->getFilename(),
-      //Url::fromUri(file_create_url($file->getFileUri()))
-	  Url::fromUri(\Drupal::service('file_url_generator')->generateAbsoluteString($file->getFileUri()))
+      // Url::fromUri(file_create_url($file->getFileUri()))
+    Url::fromUri(\Drupal::service('file_url_generator')->generateAbsoluteString($file->getFileUri()))

The indentation of the last line is wrong.

+   * @param array $form
+   *   Form array.

The short description is missing an article.

+   *   The form state.
    * @param \Drupal\file\FileInterface $file
-   *   (optional) The file to be deleted.
+   *   The file to be deleted (optional).

It is not necessary to write when a parameter is optional; that is evident from the code.

+    $new_file_markup = new FormattableMarkup(
+      'The new file to be used.<br />
+              Leave empty to keep the existing file.<br />
+              <strong>Important:</strong> The filename will not be changed unless you specify a new filename below.',
+      [
+        '' => '',
+      ]
+    );
+
     $form['new_file_details']['new_file'] = [
       '#title' => $this->t('New file'),
       '#type' => 'file',
-      '#description' => $this->t(
-        'The new file to be used.<br />'
-        . 'Leave empty to keep the existing file.<br />'
-        . '<strong>Important:</strong> The filename will not be changed unless you specify a new filename below.'
-      ),
+      '#description' => $this->t('@new_file_markup', ['@new_file_markup' => $new_file_markup]),
     ];

The existing code is already correct.

-    // TODO: set file_validate_extensions correctly
-    // TODO: Also check the return value of file_save_upload()[0] (could be FALSE)
+    // @todo set file_validate_extensions correctly

What follows @todo is a sentence: It starts with a capitalized word and ends with a period.

!MR2 Did the required changes mentioned in the comments

I have tested the !MR 2 there are no errors on running the PHP CodeSniffer. Marking it RTBC thanks!

The screenshots, showing the command output before and after applying the MR patch, have been attached.

Hi
