Fix EventDesition schema version usage

EventService Subscription adds `VerifyCertificate`, but it needs
to use  #EventDestination schema version 1.9.0 [1] or higher.

Before the fix, Redfish Service Validator gives the error like

```
1 failAdditional errors in /redfish/v1/EventService/Subscriptions/4022728919
1 fails errors in /redfish/v1/EventService/Subscriptions/4022728919
ERROR - VerifyCertificate not defined in schema EventDestination.v1_8_0 (check version, spelling and casing)
```

Tested:
- Redfish Service Validator passes
