Support upgradeEncoding in Password4j-based PasswordEncoder implementations #17881
Description
The Password4j-based password encoders currently return false for the upgradeEncodingNonNull method, which means they don't support automatic password encoding upgrades when configuration parameters change. This should be enhanced to properly detect when a password needs to be re-encoded with updated parameters.
