Subject: [PATCH] Custom meta tag to track spelling suggestions

For finders where we show spelling suggestions, we want to
track their page view impressions.
First part of the work is in static
https://github.com/alphagov/static/pull/1927

Here we insert the meta tag into the document head for analytics script
to pick up.
