disable required toggle when field has default value and is read only

[christianvogt]

Description

Add helper text to default values to guide the user to not store sensitive information in default values.

When the field is marked as read only with a default value, the field is unmarked as required.

How Has This Been Tested?

• enable the connection types feature flag
• create a connection type
• add a field
• make the field required and then set a default value and mark it read only
• observe the required checkbox gets unchecked when making this field read only
• save the field
• observe in the table, the toggle switch to make the field required is off and disabled

Test Impact
