Support React 19

[craquet]

Is your feature request related to a problem? Please describe.
Trying to install the react search-ui packages with react 19 fails due to mismatching peer dependencies. The search-ui packages declare react < 19 as peer dependencies. Installing is still possible via the --force flag, but could cause issues for example in the CI, where we don't want to append --force everywhere

Describe the solution you'd like
Change the peer dependencies of search-ui packages (that use react) to allow usage with react 19. See the upgrade guide, some changes might be required.

Describe alternatives you've considered
Forcing npm install with --force or --legacy-peer-deps works as a workaround but is not recommended by npm.

Additional context
I've tested my application with search-ui and react 19 and it works just fine. Might not apply to other use cases though.

I think this is the status from 2022.

Elasticsearch connector for Search UI is currently in technical preview status. It is not ready for production use.[

On the other hand it was written

Workplace Search connector for Search UI is deprecated and will no longer be supported. Please migrate to Elasticsearch Connector for continued support.

I guess we are going to stick to node Client and write own components.
