[TimeStampable] symfony/clock use instead of new DateTime

[adapik]

I would like to have a optional symfony/clock integration with Timestampable, now the DateTime object created with new, so we have no option to mock them in tests.

This can only be done in the bundle once the extensions have support for using a PSR-20 clock. Otherwise, there is no way for the bundle to configure it to use it. So you should request that to the extensions first.

As of the package's 3.15 release, a clock can be injected. See https://github.com/doctrine-extensions/DoctrineExtensions/pull/2760 for reference.
