fix(button): Replace incorrect confirm button blue image with coded component example
The two button examples were using images, but the rendering was slightly off causing the blues to look different for some reason.
This MR utilizes a coded button as the example. It has the possibility of becoming outdated because its hardcoded, but it is a closer match than the images were, which could also become outdated.
Closes #818 (closed)
