RFR: 8367348: Enhance PassFailJFrame to support links in HTML

[Weijun Wang]

Add HTML link processing ability in instructions. For example:

PassFailJFrame.builder()
        .instructions(htmlWithLinks)
        .addHyperlinkListener(e -> {
            if (e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
                performActionOnLink(e.getDescription());
            }
        })
