Multi project versioning search not working

[Flemmli97]

Currently if using a multi project setup with additionally multiple versions then search will be unavailable for all versions except latest version.

Steps to reproduce

1. Clone this repo
2. Use the website-multi-docs setup
3. Run yarn docusaurus docs:version:community 1.0.0 to create a new version
4. Append

versions: {
  current: {
    label: "current",
  },
  "1.0.0": {
    label: "1.0.0",
  },
},

to the community plugin-content-docs plugin section to add the version to the plugin
5. Add a version selection method e.g. via a navbar item

{
  type: "docsVersionDropdown",
  docsPluginId: `community`,
}

6. Swap between the versions and see the search bar be gone for current.

hideSearchBarWithNoSearchContext: false would make it appear but search wont work cause it will not have any context
