[EEM] When 2 metadata fields belong to the same parent only one shows up.

[simianhacker]

Kibana version:

main

Original install method (e.g. download page, yum, from source, etc.):

source

Describe the bug:

If you have 2 metadata fields like host.name and host.os.name only one of the fields will be present in the data.

Steps to reproduce:

1. Ingest some data
2. Create a definition with a metadata field that shares the same parent

Expected behavior:

Both fields should show up. The issue is we need to add a check to the ingest pipeline script that breaks apart the terms response from the transform and creates a list.
