fix: remove hover styles for touch devices inside the message menu (#307)

### 🎯 Goal

On touch devices, you don't need special styles for hover action.
However, mobile OS-es still handle the `:hover` CSS selector, but it can
be confusing to the user when they accidentally activate the `:hover`
selector, this PR removes the `:hover` styles for touch devices inside
the message menu.

and `VirtualizedMessageList` components) SDKs
