…#195990)

## Summary

Sets the correct capabilities for Onboarding cards:

- Integrations: 
- capability: `fleet.read`: The only privilege a user needs to access
the Integrations page, it won't be able to install anything though.
(`fleet` is the id for "Integrations" capability, the one for "Fleet" is
`fleetv2`).

- Dashboards: 
  - capability: `dashboard.show`

- AI Assisant: 
  - capability: `securitySolutionAssistant.ai-assistant`, 
  - license: `enterprise`

- Attack Discovery (still hidden): 
  - capability: `securitySolutionAttackDiscovery.attack-discovery`, 
  - license: `enterprise`
