Use Doctrine Migrations STABLE

[bugalot]

Goal 1: Migrate to beta1/stable and remove dependencies to @internal classes
The first goal is to replay all validation scenarios on Doctrine Migrations beta1. Most of the effort was to remove the dependency from oat-sa/tao-core to Doctrine\Migrations\MigrationRepository which is an @internal class, meaning that bacwkard compatibility is not a promise...

And indeed, between alpha1 and beta1, the interface got broken, so we cannot afford to extend this class so we found a little bit of a hack. Icing on the cake, the code is reduced.

Goal 2: Provide the addReport() method
As mentioned in https://oat-sa.atlassian.net/wiki/spaces/OAT/pages/380764311/1+PR+Review+Case+Study+-+New+Updater#No-More-Reports we found a regression. No more Reports allowed, as in the previous updaters. We identified this as a regression and implemented a basic support of this feature.

I couldn't confirm one acceptance criteria: A scenario in our Case Study reflects the change.

Please see scenario B taoUpdate.php output. in taoQtiTest Scenario B PR you will find two reports using the feature (use this branch for the tao-core one)

Thank you for the changes! If you could revert the stubs to mocks which I believe I made you to do (sry dude :), PR could be accepted.
