Chef 13 Upgrade: Rubocop Changes for Word Array Literals (`%w`)

As part of an upgrade from Chef 12 to Chef 13, this is one of the posts in which I've been detailing the issues I've encountered, and how I've resolved them.

One recommended change with the new version of Rubocop is the error %w-literals should be delimited by [ and ].

For instance:

-arr = %w(this is an array)
+arr = %w[this is an array]

For most cases, you will be able to perform one of the following commands:

# use Rubocop's automagic autocorrect, if possible
rubocop --auto-correct
# or fall back to a search and replace
find . -iname "*.rb" -exec sed -i 's/%w(\([^)]*\))/%w[\1]/g' {} \;
