Unable to start Kibana Elasticsearch for development with Fleet Experience

Hello,

I am following docs for [Development process for Fleet UI](https://github.com/elastic/integrations/blob/main/docs/extend/developer-workflow-fleet-UI.md) and it's not working as expected. The error I am seeing is:
```
[2026-04-09T16:47:08.968+02:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. socket hang up - Local: 127.0.0.1:59340, Remote: 127.0.0.1:9200
```

Is this a known issue? Or is the docs out of date?

Commands executed:
```
git clone https://github.com/elastic/kibana.git kibana
cd kibana/
git checkout v9.3.2
nvm use
Found '/home/dot-mike/test/kibana/.nvmrc' with version <22.22.0>
Now using node v22.22.0 (npm v10.9.4)

yarn kbn bootstrap
```

Then start Elasticsearch: `yarn es snapshot -E xpack.security.authc.api_key.enabled=true`

Now start Kibana and see error: `yarn start --xpack.fleet.enabled=true --no-base-path`
