Alias key in bolt inventory show --detail only shows alias from rightmost target definition

[lucywyman]

Describe the Bug

If a target is defined multiple times with different aliases in an inventoryfile, the aliases are merged and the target can be run using any alias (https://github.com/puppetlabs/bolt/blob/master/lib/bolt/inventory/group2.rb#L416). However when printing the target, regardless of which alias is used, only the alias defined in the rightmost definition will be printed.

---
version: 2
groups:
  - name: foo 
    targets:
      - name: localhost
        alias:
          - printed
          - boop
  - name: bar 
    targets:
      - name: localhost
        alias: also_printed

Expected Behavior

The --detail output should list aliases from all groups a target is a member of.

Steps to Reproduce

For example with this inventory, bolt inventory show --detail will output the same result for -n all, -n localhost, -n printed, -n boop, and -n also_printed, which is:

  "targets": [
    {
      "name": "localhost",
      "uri": null,
      "alias": "also_printed",
...
