fix(DEX2-898): Break up reveal and transition animation props

[avocado-cb]

What changed? Why?

I have noticed that at various times the chart animations have been disabled by developers to avoid odd looking transitions from new candles: Example Instance. However this also disables the reveal animation as collateral damage.

This breaks up the prop into 2 to allow disabling only transitions.

Reveal animation shown below.
