Update search results breadcrumbs and remove icons

[codedbychavez]

Description

• Add a "Config V1 (legacy)" label to V1 Docs in the search results breadcrumbs.
• Use the 2nd breadcrumb item from the Doc pages as the lvl0 label. If it is a V1 document, it is appended to the "Config V1 (legacy)" text.
• Remove the page icon emoji from the results in the search page (the search modal/dialog remains unchanged).
• Removed "News & Product Updates" as a possible lvl1 header since it is already used as the 2nd breadcrumb item.
• Remove the results count from the "See all results" text in search modal/dialog via CSS.
