BarChart borderSkipped types wrong

[a47ae]

Expected Behavior

I can set borderSkipped for bar charts to false when using typescript.

Current Behavior

The BarOptions interface defines the following type for borderSkippedoption

borderSkipped: 'start' | 'end' | 'left' | 'right' | 'bottom' | 'top';

But the documentation also defines false als possible value.
false also works as expected, so it should be included in the type definition.

Possible Solution

Change the type declaration
