fix(amazonq): respond in chat right away when user enters JDK path

[dhasani23]

Problem

On a VS Code instance backed by CloudFront, when users enter their JDK path, it takes our chat 30+ seconds to respond.

Solution

Sleep for 0.5s to allow the JDK path to be processed (i.e. we make sure it exists) and to allow the multiple chat messages to be sent.
