docs: Adding interval autoplay disable notes (#1723)

There is a good explanation in the Uncontrolled Carousel section about disabling autoplay, but I want to add something similar for the standard Carousel props section. This clarifies that setting interval to false disables autoplay.

Helps clarify GH issue #1060, though issue is already closed.
