[Fix] java, javascript parsers in openfunctions-v2

[CharlieJCJ]

Context: Parser is used to convert model response str -> OpenAI compatible function_call

• Corrected edge cases with new keyword
• Corrected [Class.]method optionally include Class in method.
• Add recursive logic in traverse_node java parser, to special handle strings
• Corrected initialization with ArrayList, Array keywords formatting.
• Additional comments, example usage and expected outputs included.

Example: PmsProductServiceImpl.updateNewStatus(ids=new ArrayList<Long>(Arrays.asList(101L, 202L, 303L)), newStatus=2) -> {'function': {'name': 'PmsProductServiceImpl.updateNewStatus', 'parameters': {'ids': 'new ArrayList<Long>(Arrays.asList(101L, 202L, 303L))', 'newStatus': '2'}}}
