fix(docs-infra): improve `search-results` layout on smaller screens (#31390)
fix(docs-infra): improve `search-results` layout on smaller screens (#31390)

Previously, the `search-results` layout was switch from horizontal to
vertical at 480px. Yes, since some search queries can yield more than 5
`.search-area`s, even 600px are too narrow to accomodate a horizontal
layout.

This commit changes the breakpoint at which the layout switches to
vertical from 480px to 600px.
