Use an "each" loop to give each person an email address that consists of their
first name + last name @ gmail.com. For example, Bob Jones will have an email
of bobjones@gmail.com. The program should end with: p people so that you can
see if the correct modifications were made to each hash.
The result should be:
[
  {
    "first_name" => "Bob",
    "last_name" => "Jones",
    "hobbies" => ["basketball", "chess", "phone tag"],
    "email" => "bobjones@gmail.com"
