Remove numeric comparison operators from DateTime

The numeric comparison operators were previously documented here because they were specifically implemented for this type.

However, this changed with rakudo/rakudo@72856df .

Now, the fact that this type can be used with these operators is simply a natural consequence of the provided coercion.
