Subject: [PATCH 1/2] Change JDK version to 21

The formatting style option `preserveBlankNodeLabelsAndOrdering` is added that governs whether the ordering and labels of blank nodes found in the source document is to be used or overriden according to the result of the stable blank node ordering algorithm. When `false` rdf parsing is done without using the blank node aware parser necessary for preserving ordering and labels.
