Don't hit GitHub during bok-choy test runs

Description

The doctests for bok-choy now routinely fail on attempts to load a GitHub page, probably because we're hitting it often enough to be throttled (especially because of multiple parallel Travis workers). Fix these tests/examples to use something that works more reliably. Example of the problem:

doc run-test: commands[5] | python docs/code/round_3/test_search.py
./home/travis/build/edx/bok-choy/.tox/doc/lib/python3.6/site-packages/urllib3/poolmanager.py:97: ResourceWarning: unclosed <socket.socket fd=5, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6, laddr=('127.0.0.1', 50152), raddr=('127.0.0.1', 50417)>
