docs: rename the Semantic Search sidebar group to Search (#4862)

The Search group covers full-text and hybrid search as well as vector
search, and full-text search is lexical, not semantic. This renames the
group to "Search" in the sidebar and in the Embedded vs Enterprise
comparison table.

`mint validate` and `mint broken-links --check-anchors` pass on the
assembled site.
