StyleGuideBaseURL can't be set on nested departments

[tas50]

Expected behavior

Full disclosure: I might be missing something here. Trust but verify.

So #7295 enabled setting the StyleGuideBaseURL config at the department level, which is great because I have 200 cops in a few different departments and I want to push users to our docs when they encounter those cops. It's not really something I want to include in the config 200 times. Per department is 😘.

The problem is I have nested departments like Chef/Style/UsePlatformHelpers

In the config if I set

Chef/Style:
    StyleGuideBaseURL: https://docs.chef.io/whatever

and then later define the cop with a StyleGuide config like this:

Chef/Style/UsePlatformHelpers:
  Description: Use platform? and platform_family? helpers to check node platform in resources and recipes
  StyleGuide: '#chefstyleuseplatformhelpers'
  Enabled: true
  VersionAdded: '5.6.0'
  Exclude:
    - '**/metadata.rb'
    - '**/libraries/*'
    - '**/Berksfile'

You would think I'd end up with:

R: [Correctable] Chef/Style/UsePlatformHelpers: Use platform? and platform_family? helpers to check a node's platform (https://docs.chef.io/whatever#chefstyleuseplatformhelpers)
      version << rhel_append_version if node['platform_family'] == 'rhel' &&
                                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Actual behavior

You get the BaseURL defined in AllCops in the rubocop project config:

R: [Correctable] Chef/Style/UsePlatformHelpers: Use platform? and platform_family? helpers to check a node's platform (https://rubystyle.guide#chefstyleuseplatformhelpers)
      version << rhel_append_version if node['platform_family'] == 'rhel' &&
                                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If I change it at the AllCops level in my config it works fine, but not at the department level.

RuboCop version

This is in within Cookstyle in a RuboCop 1.9 branch here: https://github.com/chef/cookstyle/tree/1.9

$ [bundle exec] rubocop -V
1.9.0 (using Parser 3.0.0.0, rubocop-ast 1.4.1, running on ruby 2.7.2 x86_64-darwin20)
  - rubocop-performance 1.9.2

As always to everyone here. RuboCop is amazing. Thanks for everything you do.
