Symfony version(s) affected: 4.3.1

Description
ORA-01858: a non-numeric character was found where a numeric was expected

How to reproduce
Implement Messenger with Oracle

Possible Solution
If we remove \T from $dateTime->format('Y-m-d\TH:i:s'); in \Symfony\Component\Messenger\Transport\Doctrine\Connection::formatDateTime, it works.
I think it is a special things from Oracle, is there any specifity for format datime in relation to the database?

Could we use \Doctrine\DBAL\Types\DateTimeType instead?
