Fix(AmazonQ): CodeWhisperer settings persist across restarts (aws#5283)

The intValue and StringValue used by the state class were missing the
@get:Property tag that the value property had, which meant they were not being properly serialized in the xml file.

Adding the annotation tag to the other properties allows for serialization of these values on IDE exit.
