Describe the bug

We have upgraded keycloak from 26.1.4 to 26.2.5 and we started facing following error on startup.

ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: java.lang.IllegalArgumentException: Unable to configure TLS reloading - The reload period cannot be less than 30 seconds

This error occurs because of following parameter with value -1. It is working fine with other values greater than 30 like 30s, 60m, etc
KC_HTTPS_CERTIFICATES_RELOAD_PERIOD=-1

For our need, we want to keep it -1 and keycloak documentation also allows -1, which means reloading is disabled. But still it is failing for value less than 30 seconds.

It was working fine with same value for this parameter in 26.1.4.

Is there any change from 26.2.0 or it is a bug?
