For example,convert cavesandcliffs:deepslate to quark:deepslate, their dictionaries all include forge: stone and cavesandcliffs:deepslate. I've been trying for a long time but haven't figured it out. Can you help me answer this question

You'll probably want to use the tagSplits or customtags fields to make your own tags to be unified. tagSplits was designed for this exact use case!
