Can you fix grammatical error: Change "a latest version of the same" to "the latest version of the same".

Summary
Unit tests on Python pypy and pypy3 have been failing consistently for quite some time. On detailed investigation, cryptography package is required by the requests[security] module. Although the latest cryptography version does support pypy, it doesn't build for some reason.
Setting cryptography package to a static previous version revealed that Python 3.4 support has been dropped after cryptography 2.8.
Therefore, instead of modifying requirements file, we install the correct working version of cryptography in before_install phase of pyp build.
Test plan
All checks continue to pass.
