Fix: MySQL integration tests don't need to verify CA (#98857)

* Fix: MySQL integration tests don't need to verify CA

The _better_ solution here is to use our own, custom CA certificate. But there is also no real problem in risking a MITM
attack here as it's just test code, with no sensitive data, and it's ran on our own infra (so if we have a MITM problem,
we have even bigger issues...).

* Chore: make drone
