fix: merge LanguageTool language-module.properties in shadow JAR

DuplicatesStrategy.INCLUDE caused multiple language-module.properties
entries in the shadow JAR. Java classloader picked only the last one
(Russian), so TypoDiagnostic failed with 'en-US is not a language code
known to LanguageTool'.

Add PropertiesFileTransformer with Append merge strategy to properly
combine all LanguageTool language classes into a single properties file.
