Description of the problem:
Creating the orchestrator CR in 1.4-rc2 with rhdhOperator.enabled: false and not defining rhdhOperator.subscription.sourceName fails with the following error:

- lastTransitionTime: '2025-01-02T11:50:51Z'      
  message: |        
failed to install release: values don't meet the specifications of the schema(s) in the following chart(s):        
orchestrator:        
- rhdhOperator.subscription: sourceName is required      
reason: InstallError      
status: 'True'      
type: ReleaseFailed 

 If rhdhOperator.enabled is set to false, it does not make sense that defining the other variables under rhdhOperator should be mandatory. This a regression as well - it worked for milestone 3.

How reproducible: 100%

Steps to reproduce:

1. Deploy RHDH 1.4

2. Deploy Orchestrator operator 1.4-rc2, and create an orchestrator resource with only the following under rhdhOperator:

  rhdhOperator:
    enabled: false 

3. Check the orchestrator's status 

Actual results:
Orchestrator installment fails:

NAMESPACE      NAME           READY   REASON
orchestrator   orchestrator   True    InstallError 

with the error reported above.

Expected results:
Orchestrator should be able to be installed with only rhdhOperator.enabled: false. Other fields, like the sonataflow operators, can be disabled and not need other sub-fields set for the orchestrator  resource to be installed.
