Some links coming from /search contain two or more slashes

Steps to reproduce:

1. Go to https://docs.gitlab.com/search/?q=sast&idx=gitlab&p=3
2. Notice the mutltiple slashes ///// in the URLs!
3. Load more results, you will see that the URLs get duplicated by / added to them multiple times.

That's strange because the search index is created by the sitemap and it doesn't contain any double slashes https://docs.gitlab.com/sitemap.xml.

It seems this is an Algolia issue. It happens only on the /ee, Runner and Omnibus links are fine.
