feat: update Saxon library to v11.4
This commit updates the Saxon-HE dependency to version 11.4. It refactors the Saxon-related code as follows: - update the function+registration code to the latest API changes - extract the Saxon schema reader factory (used by Jing) in its own class - the Saxon schema reader factory is made available to Jing via the SPI mechanism (declared in `META-INF/services/com.thaiopensource.validate.SchemaReaderFactory`). This notably allows Jing to find and use our factory for both Schematron and NVDL. - the Saxon schema reader factory no longer extends Jing's `NewSaxonSchemaReaderFactory`, which set the feature "XSLT_VERSION" to "2.0" and caused a Warning to be issued by Saxon 11. Fix #1341
