<Swing Dev> RFR: 8264398: BevelBorderUIResource​(int, Color, Color) spec should mention that the passed colors are for highlightInner and shadowOuter props

[Prasanta Sadhukhan]

The current spec for javax/swing/plaf/BorderUIResource.BevelBorderUIResource.html(int,java.awt.Color,java.awt.Color) does not clearly specify the usage of color for hightlight and shadow as there are outer/inner hightlight and outer/inner shadow.
Updated spec to clarify the same.
