(GH-3309) Ensure bundled-ruby defaults are applied at target init

Previously defaults were not applied until an action was actually requested on a target. This made inventory resolution confusing and non-determanistic behavior with apply_prep. This commit moves application of defaults for a target to the init method for creating a target object.

* **Apply bundled-ruby defaults at target creation** ([#3309](3309))

  Ensure defaults associated with `bundled-ruby` transport config are
  applied at target initialization.
