Docs: Misplaced automatic keyword highlighting

[TimoEckstein]

Description of the issue
In the documentation, it seems that some keywords are automatically highlighted out of context. This occurs when the code example is not pure python code. Examples are:

• https://quantumai.google/cirq/install, "get" and "base" are highlighted blue

sudo apt-get install texlive-latex-base latexmk

• https://quantumai.google/cirq/dev/development, "from", "last","and" and "for" are highlighted blue

add2virtualenv <paste modules from last command>
./check/pytest [files-and-flags-for-pytest]

Cirq version
cirq.master

Thank you for reporting this issue (so long ago!)

This appears to have been fixed at some point since then. Consequently, closing this issue.
