you can't add a new certificate to "system roots", it's read-only.
add it to "System"

Open the Keychain Access app and drag that file into the System folder of that app.
Find the ISRG Root X1 certificate in System and double click on it, open the Trust menu and change "Use System Defaults" to "Always Trust", then close that and enter your password to confirm the change (if prompted).
