Description of problem:
Subscription and trigger form Add button is disabled on opening the form if dropped on KSVC from channel/broker. Since required field is pre-populated the Add button should not be disabled as the user might not want to change anything and straightaway create the resource.
The Add button is disabled since the form is not `dirty`.
Prerequisites (if any, like setup, operators/versions): Install Serverless operator
Steps to Reproduce
- Create a channel/broker
- Deploy an image as knative resource
- hover on channel/broker drag and drop on KSVC created above
Actual results:Add button is disabled
Expected results:Add button should not be disabled
Reproducibility (Always/Intermittent/Only Once): Always
