Simplify dependency in inspec.yml

[chris-rock]

Description

Currently we already support various targets for dependencies, but the description is quite verbose.

depends:
  - supermarket: hardening/ssh-hardening
  - compliance: base/linux
  - name: os-hardening
    url: https://github.com/dev-sec/tests-os-hardening/archive/master.zip
  - name: ssl-benchmark
    git: https://github.com/dev-sec/ssl-benchmark.git
  - name: windows-patch-benchmark
    git: https://github.com/chris-rock/windows-patch-benchmark.git
  - name: linux
    compliance: base/linux

We should support a simplification of the above as a shortcut for the user:

depends
  - name: hardening/ssh-hardening # default is supermarket
  - supermarket: hardening/ssh-hardening
  - compliance: base/linux
  - git: https://github.com/chris-rock/windows-patch-benchmark.git
