Version 3.5.7 UpdateX509 Not Compatible with Keycloak 26.1.2 and BouncyCastle FIPS

[p1-bot-repo-sync]

When using version 3.5.7 and Keycloak 26.1.2 in FIPS-enabled mode (BouncyCastle FIPS libraries), the UpdateX509 action crashes:

I understand that 3.5.7 is not intended to support Keycloak 26, but my team had to upgrade to be compliant with IAVA releases. Simply upgrading the plugin might fix this.
