content: show actual value of numeric constants

The code example for the Numeric Constants slide uses the
right and left shift operators, which some people are
unfamiliar with.

Showing the values of the constants in a comment lets
people grasp the point of the slide without being distracted
by not understanding the shift operators.

Fixes golang/go#14151
