[Bundles][DoctrineMigrationsBundle] update

[X13454]

Hello,

Looking at http://symfony.com/doc/master/bundles/DoctrineFixturesBundle/index.html, there is only one require. The dependencies being managed by https://github.com/doctrine/DoctrineFixturesBundle/blob/master/composer.json.

{
    "require": {
        "doctrine/doctrine-fixtures-bundle": "2.2.*"
    }
}

However in http://symfony.com/doc/master/bundles/DoctrineMigrationsBundle/index.html, we have:

{
    "require": {
        "doctrine/migrations": "1.0.*@dev",
        "doctrine/doctrine-migrations-bundle": "2.1.*@dev"
    }
}

Shouldn't the doctrine/migrations dependency be handled only by https://github.com/doctrine/DoctrineMigrationsBundle/blob/master/composer.json ? It would avoid a repetition.

Kind regards
