[Fleet] Added default index pattern creation to stream-based installation (#199122)

**Related to: https://github.com/elastic/kibana/pull/195888**

## Summary

Add default index pattern creation to the new stream-based package
installation method to match the behavior of standard package
installation.

Switching to stream-based package installation resulted in the default
index patterns not being created, even after installing the rules
package. While this likely doesn’t affect production, as multiple
integrations are usually installed in Kibana (creating the default index
pattern in any case), this change has impacted some tests:
https://github.com/elastic/kibana/pull/199030. So restoring the original
behaviour
