Don't enforce double-quotes for strings.

There are times when it's appropriate to use single quotes.
Specifically when maintaining consistency within an area of the
codebase (this linter it typically only applied to the diffs, and
therefore won't take into account existing uses of single-quotes - eg
alphagov/whitehall#2270).  It therefore doesn't
make sense to enforce this automatically.
