fix: 🐛 canvas is not cleaning up when switching slides

When using DeckBuilder and adding slides via withSlide() methods there,
it creates each slide with its own canvas representation. It leads to
the problem, when deck is not able to clean up canvas when switching
slides back and forth. This commit fixes an issue by passing the right
canvas from Deck instance through SlideBuilder.withCanvas() method.
