[CT-2680] [Bug] Allow referencing private models within dbt show "inline" queries

[jtcohen6]

Currently, dbt will raise a DbtReferenceError when trying to preview an --inline query that refs a private model, because the inline query is not part of the same model group as the private model.

In my opinion:

• It should be possible to preview a private model, or a query that references that model
• If you then save that query in a model in a different group, you'll start seeing the reference error — which makes sense!

Reproduction case

groups:
  - name: my_cool_group
    owner:
      name: Me

models:
  - name: my_model
    access: private
    config:
      group: my_cool_group

$ dbt show --inline "select * from {{ ref('my_model') }}"
22:51:45  Running with dbt=1.6.0-b2
22:51:45  Encountered an error:
Parsing Error
  Node sql operation.my_dbt_project.inline_query attempted to reference node model.my_dbt_project.my_model, which is not allowed because the referenced node is private to the my_cool_group group.

(While here: let's change the string rendering of sql operation to something without spaces - sqloperation)
