Grails 7 migration issue with spring-security-saml4.0.2 plugin

### Expected Behavior

During Grails 7 migration we see issue with latest grails plugin org.grails.plugins:spring-security-saml:4.0.2 , our integration tests fails with following exception, this is because latest version of grails plugin spring-security-saml still using old classes in javax.servlet from javax.servlet-api-4.0.1.jar instead of "jakarta.servlet." from jakarta.servlet-api-6.0.0.jar can you share the the latest version of grails plugin spring-security-saml supporting jakarta.servlet-api:6.0.0

Start with the spring-security-saml:4.0.2 dependency and the javax.servlet versus jakarta.servlet versions described in the report. Inspect XYZSamlLogoutFilter.groovy at line 133 and XYZSamlLogoutFilterTest.groovy around line 180, then run the failing integration test. Done means establishing whether a Grails 7-compatible plugin version exists or documenting the compatibility limitation.
