Incorrect parameters used for the @JRuleWhenItemChange trigger in the examples

[nelsonaponte]

Many of the examples use the @JRuleWhenItemChange but mention that a JRuleOnOffValue type should be passed as arguments to the 'to' and 'from' parameters:

`import static org.openhab.automation.jrule.rules.JRuleOnOffValue.ON;
import static org.openhab.automation.jrule.rules.JRuleOnOffValue.OFF;

...
@JRuleWhenItemChange(item = MyTestSwitch2, from = OFF, to = ON)`

Yet, the variables are of type String

The compiler finds and reports the error:
