Custom Fields assigned to Config Plans are not editable and present during the plan creation

[georgkal]

Environment

• Python version: 3.9
• Nautobot version: 1.6.2
• nautobot-golden-config version: 1.6.2

Expected Behavior

Once a custom field is created and assigned to type: nautobot_golden_config | config plan, i am expecting this field to be present under the config plan and to be editable.

Observed Behavior

Once a custom field is created and assigned to type: nautobot_golden_config | config plan, field is not visible during the config plan creation and it cannot be filled/updated. Also, once you open already created Config Plan, field is visible in the GUI/API but clicking the edit button(respectively making a PUT/PATCH), custom field is not present at all and cannot be edited.

Steps to Reproduce

1. Create Custom Field and assign it to type: nautobot_golden_config | config plan
2. Create new Config Plan of any type and custom field is not present there
3. Open any existing config plan, and custom field is present in the GUI, but clicking "edit" you cannot see it and edit it
