[EPM][Ingest Manager][Bug] Support package index_patterns

[jonathan-buttner]

The package registry no longer supports defining asset directories with a dash -. This PR: #70320 switched many of the dashes to underscores. It didn't switch the index-pattern kibana saved object type: https://github.com/elastic/kibana/blob/master/x-pack/plugins/ingest_manager/common/types/models/epm.ts#L30

I tried switching it locally but I believe it needs to be set to index-pattern when being used in the bulk savedobject request to save the asset: https://github.com/elastic/kibana/blob/master/x-pack/plugins/ingest_manager/server/services/epm/packages/get_objects.ts#L24 .

The easiest fix I can think of is checking in that function to see if the type is index_pattern and changing it to index-pattern. I'm not sure if this is going to mess with anything else though.
