MT#63228 Restore setPreference behavior to pre-716d45f6 state

Revert changes from commit 716d45f6 that altered setPreference.
The previous commit limited the function to handling only true/false
preferences, removing the ability to replace existing values.
This change restores the original behavior, allowing setPreference
to update existing preferences with new values, not just booleans.
