[Infra] fix serverless link (#178728)

## Summary

Closes https://github.com/elastic/kibana/issues/178645

Introduced in https://github.com/elastic/kibana/pull/176539, the link
for the user to take further action is pointing to a page that does not
exist in serverless. This updates the link depending on the environment.
It will continue to point the link to the apm tutorial
(`/app/home#/tutorial/apm`) in non serverless and point to onboarding in
serverless (`/app/apm/onboarding`)
