@algolia autocomplete-shared throws a warning regarding 'render' option

[jkohlin]

Please describe the bug you are seeing

I get this warning when adding the plugin in docusaurus v2.1.0

[Autocomplete] You provided the 'render' option but did not provide a 'renderer.render'. Since v1.6.0, you can provide a 'render' function directly in 'renderer'.
To get rid of this warning, do any of the following depending on your use case.
- If you are using the 'render' option only to override Autocomplete's default 'render' function, pass the 'render' function into 'renderer' and remove the 'render' option.
- If you are using the 'render' option to customize the layout, pass your 'render' function into 'renderer' and use it from the provided parameters of the 'render' option.
- If you are using the 'render' option to work with React 18, pass an empty 'render' function into 'renderer'.
