aider: Replaced MarkdownLexer with PygmentsLexer to correctly highlight user input with markdown syntax.

Browse source 
# Context:
USER: AttributeError: 'MarkdownLexer' object has no attribute 'lex_document'
ASSISTANT: I apologize for the confusion. It seems I misunderstood the usage of `MarkdownLexer` with `prompt_toolkit`. Instead, we should use `PygmentsLexer` from `prompt_toolkit.lexers` to wrap the `MarkdownLexer`. Here's the updated change:

First, import `PygmentsLexer` from `prompt_toolkit.lexers`:

```python
aider/io.py
<<<<<<< ORIGINAL
from prompt_toolkit.completion import Completer, Completion
=======
from prompt_toolkit.completion import Completer, Completion
from prompt_toolkit.lexers import PygmentsLexer
>>>>>>> UPDATED
```

Then, update the `PromptSession` instantiation in the `get_input` method:

```python
aider/io.py
<<<<<<< ORIGINAL
            session_kwargs = {
                "message": show,
                "completer": completer_instance,
                "reserve_space_for_menu": 4,
                "complete_style": CompleteStyle.MULTI_COLUMN,
                "input": self.input,
                "output": self.output,
                "lexer": MarkdownLexer(),
            }
=======
            session_kwargs = {
                "message": show,
                "completer": completer_instance,
                "reserve_space_for_menu": 4,
                "complete_style": CompleteStyle.MULTI_COLUMN,
                "input": self.input,
                "output": self.output,
                "lexer": PygmentsLexer(MarkdownLexer),
            }
>>>>>>> UPDATED
```

These changes will correctly use the `MarkdownLexer` with `prompt_toolkit` to highlight the user input with markdown syntax.
