[FEATURE] Support horizontal scrolling of code examples within prompt

[stephanj]

Currently we need to make the window bigger to see the right side of the code examples.
We could just introduce a CSS text-wrap instead.

Just got this problem as well and the Devoxx Genie window -- at least for RustRover -- does not contain a horizontal scrollbar:

If you have a starting point on how to introduce this "feature", I might be able to take a look myself :)

The main logic for the response output is located in PromptOutputPanel.java
