Include Hash#size in the examples
Both methods Hash#length and Hash#size share the same source code in Ruby, but they also share the same documentation. Now when you look at the documentation of Hash#size you only see examples for Hash#length, which is confusing. This commit includes Hash#size in the examples and also remarks that both methods are equivalent to each other.
