Update deprecated code in va_gov_migrate Commands.php

[omahane]

User Story or Problem Statement

According to Drupal:
docroot/core/lib/Drupal/Core/Entity/EntityStorageInterface.php:

/**
   * Delete a specific entity revision.
   *
   * A revision can only be deleted if it's not the currently active one.
   *
   * @param int $revision_id
   *   The revision id.
   *
   * @deprecated in drupal:10.1.0 and is removed from drupal:11.0.0. Use
   * \Drupal\Core\Entity\RevisionableStorageInterface::deleteRevision instead.
   *
   * @see https://www.drupal.org/node/2926958
   * @see https://www.drupal.org/node/2927226
   * @see https://www.drupal.org/node/3294237
   */
  public function deleteRevision($revision_id);

We are using this function in va_gov_migrate/src/Commands/Commands.php, line 127
$this->entityTypeManager->getStorage('node')->deleteRevision($vid);

Description or Additional Context

It's unclear when we're moving to Drupal 11 or what the plan is for that.

The last time this code was updated was for the Drupal 9 upgrade.

Steps for Implementation

Use the replacement function in the Commands.php file.

Acceptance Criteria

• va_gov_migrate should not present any issues with an upgrade to Drupal 11 in the Upgrade Status report.
