Add an inline Instructor Note warning about different flag behaviour

[tobyhodges]

The general Instructor Notes mention that

grep -E on macOS X acts like grep -P on other platforms. On Windows and Linux, grep -E is halfway between grep -P and grep: it only does what grep can do, but uses Perl-compatible syntax to do it.

This pull request adds an inline Instructor Note to display this information next to the exercise where this confusion is most likely to be encountered.
