[General] Change Touchable default underlay props

[j-piasecki]

Description

Changes the default props of Touchable component:

• underlayColor: black -> transparent
• activeUnderlayOpacity: undefined -> 0.105 (matching RectButton)

This way, in order to replicate the RectButton, the usage is:

<Touchable underlayColor="black" />

instead of

<Touchable activeUnderlayOpacity={0.105} />

which seems more intuitive.

Test plan

Updated Touchable example

I've mixed feelings about it, currently it's like having animation, but not really since it is transparent. But on the other hand I guess the same can be said about default underlayColor.
