Save follow same logic as Test and Connect (allows save when req parameters are met, can change this easily)

Follow up to: #8636 (comment)
as Save Anyways caused mulitple keys to be created in .env.

Save is a step forward for "Edit connector" feature as it doesnt require a test connect to fail for the button to appear.
