It was a good decision in hindsight to keep the public module as 0.x
because this would have been a breaking change again.
https://mattermost.atlassian.net/browse/MM-53032
```release-note
Changed the Go module path from github.com/mattermost/mattermost-server/server/v8 to github.com/mattermost/mattermost/server/v8.
For the public facing module, it's path is also changed from github.com/mattermost/mattermost-server/server/public to github.com/mattermost/mattermost/server/public
```
This will be shown in the system console to let users know
which search backend is active.
Implemented via adding an extra param in the ping response.
https://mattermost.atlassian.net/browse/MM-49984
```release-note
The database section in the system console now has an additional
read-only section which shows the active search backend in use.
This can be helpful to confirm which is the currently active
search engine when there are multiple of them configured.
