Reverse order of URL bar context menu items when using bottom bar

[kylehickinson]

Description:

When you are using bottom bar we should reverse the order of the menu items when you long press and display the context menu. This will mean that the Paste & Go/Paste commands will be closer to your finger instead of on the opposite side

This will be more common in iOS 16 as they introduced a API to do this for you.
