ARIA Practices Guide breaks search

[yatil]

When searching for a phrase present in the ARIA Practices Guide documentation, I get many entries that do not contain a link to the search result. The reason is that the search uses front matter information to put these results together. The APG uses HTML documents that do not follow the template.

Example: https://www.w3.org/WAI/search/?q=landmarks

How to fix:

1. Make APG follow the template and add expected metadata
2. Remove APG from the search index.

See alternative solution in #362, which is a solution that targets the 12 problematic pages in the APG. The APG Task Force will resolve the issues with the problematic pages so that we can later undo their exclusion from search.

@yatil Thanks for raising the issue.

I have just merged and deployed #362 temporary fix to exclude the concerned pages.
