Limit the fabric label to 32 characters in the Pythin Matter server

[Apollon77]

The fabric label can be set via websocket command (code reference:

python-matter-server/matter_server/server/device_controller.py

Line 296 in 0873350

@api_command(APICommand.SET_DEFAULT_FABRIC_LABEL)

).

We need to make sure that the provided label is maximum 32 characters long. So the value needs to be cutted at that length. Additionally please log a info logline that this was cutted if it was longer
