Remove Container Workload Protection link from Assets page (elastic#2…

…00895)

## Summary

Closes elastic/security-team#10741.

As the name suggests, it simply removes the link to the "Container
Workload Protection" link from the Cloud section in the Assets page. The
Cloud section is kept though, since the screenshot in the ticket doesn't
highlight it.

### Testing

> [!NOTE]
>  Note this page is only accessible in Serverless.

Authenticate to Docker Registry with
```bash
docker login -u albertoblaz -p <YOUR_PASSWORD> docker.elastic.co
```

Then run ES with

```bash
yarn es serverless --projectType security --kill
```

Alternatively, run Kibana with
```bash
yarn serverless-security
```

### Screenshot

Link removed, but Cloud section is kept:
