Navbar renders a useless SearchBox element when site does not have any search plugin

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

Hi, I was using the version beta .20, then I updated all my docusaurus dependencies to the latest, but, even though I haven't installed the search package or have no item of type search in my docusaurus.config, I still notice a div with searchBox_node_modules-@docusaurus-theme-classic-lib-theme-Navbar-Search-styles-module as class in my navbar. And I can't find any reference to it in my project.
It's just the stylings given in a css found in the node_modules, which is a media-query with min-width 997px

Can you please help me?

Yes we render a useless element here, related to #7990

We could make it possible to not have this element in the first place (preferable) but this requires an API breaking change.

We could also keep it for now, and ensure it doesn't take and space
