Replace hardcoded name with Command::getName() in output message from UpdateCommand

[phansys]

By instance, "doctrine/doctrine-bundle" defines the name doctrine:schema:update for this command, but the hardcoded value here generates a misleading message.

$ bin/console doctrine:schema:update --dump-sql

                                                                                                                        
 [WARNING] Not passing the "--complete" option to "orm:schema-tool:update" is deprecated and will not be supported when 
           using doctrine/dbal 4                                                                                        
                                                                                                                        

                                                                                                                        
 [OK] Nothing to update - your database is already in sync with the current entity metadata.

Have you considered writing a test for this?

No, but I think I can try.

Good catch. Is this the only command where we've hardcoded the command name in some message?

I think so, I couldn't find other similar occurrences.
