feat: remove customRippleColor from components

[adrcotfas]

Motivation

• We're modernizing Paper to support PlatformColor for Dynamic Themes without native modules which does not support applying an alpha to it, something required for the current implementation of ripple color.
• Dynamic Themes using PlatformColor and custom ripple color is not compatible.
• MD3 guidelines specify that ripple color is derived from the content color, not a custom color so the question "why do we need to support that" comes to mind.
• The current ripple implementation in components like Button, IconButton, SearchBar, Chip etc does not follow the MD3 guidelines.
• The native Jetpack Compose library does not support adding a custom ripple color without some special CompositionLocalProvider config so custom ripples are not encouraged.
• In MD3, the default ripple color is using a 0.1 alpha applied to a neutral color. Per specs, some components like Button need a 0.1 alpha applied to a primary/tertiary color. At this opacity it's hard to distinguish the neutral from the primary ripple and we don't have a choice when using PlatformColor anyway.
• I've proposed extending android_ripple to support PlatformColor and an alpha that will allow Paper to follow the MD3 ripple specs for all components: feat(Pressable): add support for PlatformColor and alpha facebook/react-native#56395.
• These are the reasons I'm proposing we drop the custom ripple color and make our life easier for the next steps.

Test plan

Run the example app and observe the ripple color for components; Button for example will have a slightly different tint.
