Make a small tweak to readme (#1766)

The example script creating a bell state under the Creating your First
Quantum Program in Qiskit Terra section has an example of the output
after outlining the script. However, the output in that section was out
of date and doesn't actually reflect what the output dictionary from
get_counts() looks like. This just fixes that line so the output matches
the current output.
