[EPM] Include both kibana and elasticsearch assets in package information

[skh]

Summary

Fixes #85968

It was probably an oversight that elasticsearch assets weren't included in the original implementation. Half of the changes are uncommenting lines that have been commented out before.

How to test this

Verify that #85968 has been fixed

Find an integration that contains both elasticsearch and kibana assets. Navigate to that integration's detail page under Fleet->Integrations (I used Nginx for this). Observe that both kind of assets are listed on the left side:

On the integration's detail page, navigate to the Settings tab and click the "Install $INTEGRATION assets" button. Verify that the number of assets to be installed is correct:

Tested locally and works as expected.
Looking at the code looks the AssetTitleMap is not translated should we fix that and create and issue for that?

Good point. I'm not sure these strings should ever be translated:

  dashboard: 'Dashboard',
  ilm_policy: 'ILM Policy',
  ingest_pipeline: 'Ingest Pipeline',
  transform: 'Transform',
  index_pattern: 'Index Pattern',
  index_template: 'Index Template',
  component_template: 'Component Template',
  search: 'Saved Search',
  visualization: 'Visualization',
  input: 'Agent input',
  map: 'Map',
  data_stream_ilm_policy: 'Data Stream ILM Policy',

I dimly remember discussions about this, but not the result. @jen-huang do you know more?
