Entity save command does not properly check for revision support.

[Chi-teck]

To Reproduce

$ drush entity:save user

 ┌ Saving entities ─────────────────────────────────────────────┐
 │                                                              │
 └───────────────────────────────────────────────────────── 0/1 ┘


In ContentEntityBase.php line 305:
                                                
  Entity type user does not support revisions.  
                                                

I think it checks for revision support in wrong way. Implementing RevisionableInterface does not mean that entity actually supports revisions. Yes, that's weird.

I think the command should check it like follows.

$is_revisionable = $this->entityTypeManager->getDefinition($entity_type)->isRevisionable();
