[PR #12151/994b7560 backport][stable-13] java_cert: fix PKCS12 password not passed to keytool -list (#12243)

java_cert: fix PKCS12 password not passed to `keytool -list` (#12151)

* fix(java_cert): remove -noprompt from keytool -list to allow stdin password

-noprompt is not a valid option for keytool -list (only for importkeystore/
importcert). On Java 8, passing it caused keytool to skip reading the store
password from stdin, resulting in a null password and NullPointerException.

Fixes #3023



* test(java_cert): add idempotency test for pkcs12 import with password

Exercises _export_public_cert_from_pkcs12 when the alias already exists,
verifying the password is correctly read from stdin on the comparison path.



* changelog: add fragment for PR 12151
