Symfony 6.4 make:migration requires CommentHint

[Seesicht-IT]

Thanks for putting this all together! It is crazy that until now, this is not part of Doctrine...

In a Symfony 6.4 project, I noticed that the command php bin/console make:migration would always bring up the db-columns as changed and would include a line into the migration file looking something like this:

$this->addSql('ALTER TABLE admin_user_log CHANGE created_at created_at DATETIME(6) NOT NULL');

To get around this problem, I added this to BaseDateTimeMicroWithoutTz / BaseDateTimeMicroWithTz / BaseTimeMicro:

public function requiresSQLCommentHint(AbstractPlatform $platform): bool
{
    return true;
}

With this, the column will be created with a comment, in my case (DC2Type:datetime_immutable_micro) and the Maker-Bundle will recognize the column mapping correctly.

requiresSQLCommentHint() is marked as deprecated and won't be available in DBAL version 4. But as Symfony 6.4 is still using it, I was fine taking the same approach. So as soon as Symfony switches to DBAL 4 and ORM 3, this has to be reworked.
