fix(level-23): remove service name from validation

[rhotertj]

Pull Request

📝 Description

Level 23 is about fixing the connection between the database and the client by correcting a hostname mismatch.
The solution is to either rename the service to match the client's request or to change the pods command args to match the service name.

The current validation script does not allow the service name to be changed because it is hard-coded as an expected value. Although the logs report a successful connection when the service name is changed, the mission fails.
Therefore, I removed the service name from the log validation.
