Overflow for skip_updates in modbus sensors

### The problem

Hello

I have an issue with the different MODBUS sensors. When I try to specify a skip_updates value greater than 255 a warning is issued:

```
src/main.cpp: In function 'void setup()':
src/main.cpp:502:176: warning: unsigned conversion from 'int' to 'uint8_t' {aka 'unsigned char'} changes value from '2500' to '196' [-Woverflow]
502 | cancelletto_gate_time = new modbus_controller::ModbusNumber(modbus_controller::ModbusRegisterType::HOLDING, 0, 0, 0xFFFFFFFF, modbus_controller::SensorValueType::U_WORD, 1, 2500, false);
```

(in this case the issue was with a ModbusNumber, but I also experienced it with a TextSensor).

I think that the best option would be to modify the variable type, so that greater numbers can be used there (for instance I have a system where the update cycle is pretty fast - 200ms, but there are sensors which never change, so I'd like to poll them once every 10 minutes or so, while with this limitation I'm forced to update them every 50 seconds).

If this is not possible, then maybe this shall be highlighted better, because this warning can easily go unnoticed (and this is a parameter that is hard to notice is configured badly)
