Fix: lsp_bridge.py raises a KeyError when a code action is triggered in tramp.

Problem

When I triggered a code action in a file over the tramp, the lsp_bridge.py output the following error, and the code action did not work.

--- [19:54:05.515935] Recv textDocument/codeAction response (26129) from 'ruff' for project sandbox
Error when processing response 26129
Traceback (most recent call last):
  File "... /lsp-bridge/core/handler/__init__.py", line 38, in handle_response
    self.process_response(response)
  File "... /lsp-bridge/core/handler/code_action.py", line 37, in process_response
    changes = item["edit"]["changes"]
KeyError: 'changes'

Fix

The item["edit"] is assumed to be a WorkspaceEdit instance and it looks to have one of (changes or documentChanges ).
See: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#workspaceEdit

Since the current version only supports the changes case, I added an implementation to support documentChanges to fix the problem.

Note

Although I have implemented cases for all documentChanges types (TextDocumentEdit, CreateFile, DeleteFile, RenameFile), I was only able to confirm the case of TextDocumentEdit that is returned in code_action.py and rename.py. I could not test the other types, CreateFile, DeleteFile, and RenameFile, because I am not sure in what use cases lsp would return these operations.

I would appreciate it if you could confirm this.
