[Observability Onboarding] Display next steps after auto-detection completes

[thomheymann]

Depends on https://github.com/elastic/observability-design/issues/315

After the auto-detect script completes users are currently asked to go back to Kibana to view their data. Some users will want to do this but others might want to add additional inputs or edit their config to allow metrics ingestion.

We should cater for these different scenarios by highlighting next steps to users:

• Explore your data (go back to Kibana)
• If integrations were installed that require setting credentials these should be listed (show path to config file)
• Add more inputs (link to existing standalone configuration)
