Fix backgroundColor not being applied to RNGestureHandlerButton (#3368)

## Description

`RNGestureHandlerButton` consists of 2 nested `ViewGroups` -
`ViewGroupManager` and `ButtonViewGroup`

Before React Native `0.77`, `backgroundColor` was applied to
`RNGestureHandlerButton` by `ButtonViewGroup.setBackgroundColor(color)`,
which was called by unknown React Native mechanism.

In React Native `0.77` something changed, and
`ButtonViewGroup.setBackgroundColor(color)` stopped being called.

This PR overrides the setter for `backgroundColor` on
`ViewGroupManager`, and forwards the argument to
`ButtonViewGroup.setBackgroundColor(color)`.

I have not found the root cause (RN commit) of this issue, and i have no
idea what are the consequences of calling both the
`BackgroundStyleApplicator.setBackgroundColor()` and
`ButtonViewGroup.setBackgroundColor(color)`, but it seems like those two
functions were already called sequentially before `0.77`, as
`BackgroundStyleApplicator` was introduced in RN `0.76` and most likely
called `ButtonViewGroup.setBackgroundColor(color)` itself.
