PR Summary

• Removal of <profile> block for jdk11+
  This PR includes removing a particular section in the project's configuration file which was meant for handling specific settings when the project was being run with JDK version 11 and above. This change implies that specific settings for different JDK versions are no longer necessary, possibly indicating enhancements in compatibility across different versions of the JDK (Java Development Kit).

I have nothing against this change, I don't know maven well enough. Should we just be changing this to 17+?

[snuyanzin]

it looks like anyway it became useless since all the tests are passing without these flags
Thus I do not see a reason to keep with jdk17 or 21
