Missing intent value 'info' in Menu.Item prop types

[polosson]

Using info as a value for the prop intent of a Menu.item works as expected, but displays a warning in the console, saying that the prop is invalid:

Warning: Failed prop type: Invalid prop `intent` of value `info` supplied to `ForwardRef(MenuItem)`, expected one of ["none","success","warning","danger"].

I think we just need to add this value to this line:

evergreen/src/menu/src/MenuItem.js

Line 165 in 674d9a1

intent: PropTypes.oneOf(['none', 'success', 'warning', 'danger']),

Maybe it should use a global configuration array of allowed values for this prop?
