@OpenIdAuthenticationMechanismDefinition.extraParametersExpression is not evaluated

[dam-jan]

org.glassfish.soteria.mechanisms.openid.controller.ConfigurationController#buildConfig does evaluate extraParameters but it does not evaluate extraParametersExpression.

The Jakarte EE 10 documentation of OpenIdAuthenticationMechanismDefinition does not mention the result type of the EL in extraParametersExpression attribute. I'm not sure if the EL should return a String array or a String where the name=value pairs are separated by a comma (or something similar).
