Revert: Removed obselete warning about non-standard soap 1.2 #700

[jbescos]

We were discussing this @lukasj and me by zoom and he asked me to revert this because the warning is currently correct since the xml-ws spec considers SOAP 1.2 as to be supported in the future (see https://jakarta.ee/specifications/xml-web-services/4.0/jakarta-xml-ws-spec-4.0#goals ) and is currently optional (search through the spec for "SOAP 1.2" to learn more).

acceptable form of this change can be:

• full update through the XML-WS spec as well as the implementation and addition of new TCKs

or

• addition of an option to suppress warnings like this, instead of forcing it.

PR was: #700

https://jakarta.ee/specifications/xml-web-services/4.0/jakarta-xml-ws-spec-4.0#extensibility sounds like extensions can be used be are not supported in a standard way. This sounds to me like enabling extensions with wsimport -extension at all is not standard which lines up with (https://docs.oracle.com/javase/8/docs/technotes/tools/unix/[wsimport](https://docs.oracle.com/javase/8/docs/technotes/tools/unix/wsimport.html).html)

-extension
Allows vendor extensions. Use of extensions can result in applications that are not portable or that do not work with other implementations.

which means that specifying -extension in of itself should be enough to not print warnings every time an extension is used.
