fix: use correct TS types for style prop

[vonovak]

Motivation

The motivation is to be able to pass styles to the bottom sheet components the same way as with other react native components, see eg. https://github.com/DefinitelyTyped/DefinitelyTyped/blob/ff070e46d5821d3a28beed3707386677231ce204/types/react-native/index.d.ts#L2919

current situation:

The second screenshot contains valid styles, but the TS typings currently do not accept them. This change makes it so that the second example is valid too.

also removed appearanceBehavior because it does not appear to be used anywhere. Actually, animatedFooterPosition should be passed in that place - it'd be good to include some static checks in the repo's pipeline it seems 🙂

thanks @vonovak for spotting it, the dev screen used for experimenting new features and i did not fix it when updating footer component 🤦‍♂️
