Use new stories flexibility to improve components examples

Found a missing case on Carousel, https://getbootstrap.com/docs/5.3/components/carousel/#autoplaying-carou...

When the ride option is set to true, rather than carousel, the carousel won’t automatically start to cycle on page load. Instead, it will only start after the first user interaction.

Found a problem with blockquote in card.

Found a missing case with navbar.

I have created the upstream issue: https://github.com/twbs/bootstrap/issues/41292

Automatically closed - issue fixed for 2 weeks with no activity.
