[Bug]: step ca init ignores --password-file when using an existing root cert

[stew3254]

Steps to Reproduce

Generate a root certificate

cd ~
echo "test" > passwd
step ca init --deployment-type standalone --password-file passwd --dns ca.home --name Homelab --address :443 --provisioner JWK

Now, move it somewhere else and try to generate a new one using that existing root

cd ~
mv .step step
step ca init --deployment-type standalone --password-file passwd --dns ca.home --name Homelab --address :443 --provisioner JWK --root step/certs/root_ca.crt --key step/secrets/root_ca_key

Your Environment

• OS - Ubuntu 22.04.4
• step-ca Version - 0.26.1

Expected Behavior

I expected it to use my password file and automatically decrypt the key like it does when generating a new cert.

Actual Behavior

It doesn't appear to use my password file and automatically decrypt the key like it does when generating a new cert. This breaks my automation when using an existing cert because now it's looking for a user prompt.
