Add a version selector to the search results page
What does this MR do and why?
Adds a version selector to the search results page, and updates the page title to indicate that Search on docs.gitlab.com runs against the latest docs.
When the visitor picks a version, they are redirected to search results for their query on the appropriate archive site.
We have technical reasons for not using the same Google search engine for all versions of the site. At this time, our best option is to send people over to their desired archive version and run the search there, using version-scoped Lunr.js (which is already in place).
Why
- Visitors using self-managed GitLab need a way to run a search against older versions of the docs.
- It is currently unclear that search on docs.gitlab.com searches the latest docs.
