samples: matter: Fix doorlock auto-relock

ArekBalysNordic · ArekBalysNordic · commit e521a2612de9 · 2025-08-20T08:10:57.000+02:00
The Matter Lock sample did not react to auto-relock after
invoking this request by the controller.

The issue was that the callback for this feature was not
implemented in the Lock sample.
