By mistake I removed the permissions to the user ARA client 100 for the release automation. I have un-cheked in this section "User is Administrator"
How can I restore them? this section has now disappeared (Release Automation)

The admin user was created in the initial step of the installation, you can follow this link for reference 
Check the ARA's log, or config file, look for system User
in the example below, user is 100/ARA/ARA
Connection - Name: UC4; System: AUTOMIC;
    System - User: 100/ARA/ARA; Client: 100.
        Queue trigger - Agent: WIN01; Login: LOGIN.WIN01.
        Connection strings:
            MainDatabase:Data,1433;Initial Catalog=ARA;User ID=AUTOMIC;Password=*****
            DB Versions: 800201709121; 800201709081; 800201708231; 800201708171; 800201708161; 800201708141; 800201708011; 800201707251; 800201707201; 800201707191;


 Run the below SQL statement against ARA database, It will help to bring you the admin previledge 
update usr set IsAdmin='1' where id in (select id from Member where Technicalname='100/ARA/ARA')
