playground: More verbose error message

The existing error message when accessing a code snippet from an
unknown country (App Engine detected as "ZZ") have been subject for
confusion several times. I've seen many users thinking that the
particular code snippet they are trying to access contains code that
isn't legal to share, when it is only App Engine that fails to identify
their origin. Most often this is because they are behind a proxy.

This change gives a more helpful message. It is also formated in HTML as
the previous used html.Error() that showed that message as text,
verbatim.

Deployment

(Googlers only) To deploy the front-end, use play/deploy.sh.

gcloud --project golang-org app deploy sandbox/app.yaml --no-promote --version=17rc6

Use the Cloud Console's to set the new version as the default: https://cloud.google.com/console/appengine/versions?project=golang-org&moduleId=sandbox Then test that play.golang.org and tour.golang.org are working before deleting the old version.
