During processing of Release notes of https://issues.redhat.com/browse/JBEAP-25436

we noticed there is variable JBOSS_TX_NODE_ID "documented" https://github.com/wildfly/wildfly-cekit-modules/pull/391/files#diff-e76c5542a9b8fe04de4394d4bac1ed69ed2848073d675a6803c0ee820abebab6R17

But it is not meant to be used by users. And any provided value is really ignored https://github.com/wildfly/wildfly-cekit-modules/pull/391/files#diff-c3ac93a10fcd7fc91929081db8053ddc8a041bb9fa3ec7187d0c42a49ad654d9R74

So to not give false expectations to users we should get rid of that note https://github.com/wildfly/wildfly-cekit-modules/pull/391/files#diff-e76c5542a9b8fe04de4394d4bac1ed69ed2848073d675a6803c0ee820abebab6R17
