fix(matter): examples must set pin to Digital Mode after analogWrite() and before digitalWrite() (#11070)

* fix(matter): itshall set digital mode before digitalWrite

* fix(matter): example must set pin in digital mode before writting

* fix(matter): example shall set digital mode before writing

* fix(matter): digitalMode necessary before digitalWrite(LOW)

* fix(matter): example must set digital mode after analogwrite

* fix(matter): wrong copy paste

* ci(pre-commit): Apply automatic fixes
