Danger: No longer exclude Database from codeowners section for roulette

In !127907 (merged) excluded Database codeowner from roulette section to avoid duplicate labels.

We also removed database maintainers from the generic (*) codeowner rule.

!128937 (merged) re-added database maintainer for * again.

This MR allows reviewer roulette add database label based on codeowners again.
