text: Title: Mermaid Crashes If trying to draw a large pipeline
  Body: Thanks in advance for your help :)
  
  **Describe the bug**
  I was building a huge pipeline, 30 components and 35 connections, and for debugging proposes I wanted to display the diagram, but both .draw() and .show() methods failed. It still works with small pipelines by the way.
  
  **Error message**
  ```
  Failed to draw the pipeline: https://mermaid.ink/img/ returned status 400
  No pipeline diagram will be saved.
  Failed to draw the pipeline: could not connect to https://mermaid.ink/img/ (400 Client Error: Bad Request for url: https://mermaid.ink/img/{place holder for 2km long data}
  
  No pipeline diagram will be saved.
  Traceback (most recent call last):
    File "/Users/carlosfernandezloran/Desktop/babyagi-classic-haystack/.venv/lib/python3.10/site-packages/haystack/core/pipeline/draw.py", line 87, in _to_mermaid_image

      raise HTTPError(http_error_msg, response=self)
  requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://mermaid.ink/img/{another placeholder}
  
  The above exception was the direct cause of the following exception:
  
  Traceback (most recent call last):
    File "/Users/carlosfernandezloran/Desktop/babyagi-classic-haystack/babyagi.py", line 188, in <module>
      pipe.draw(path=Path("pipe"))
    File "/Users/carlosfernandezloran/Desktop/babyagi-classic-haystack/.venv/lib/python3.10/site-packages/haystack/core/pipeline/base.py", line 649, in draw
      image_data = _to_mermaid_image(self.graph)
    File "/Users/carlosfernandezloran/Desktop/babyagi-classic-haystack/.venv/lib/python3.10/site-packages/haystack/core/pipeline/draw.py", line 95, in _to_mermaid_image
      raise PipelineDrawingError(
  haystack.core.errors.PipelineDrawingError: There was an issue with https://mermaid.ink/, see the stacktrace for details.
  
  ```
  **Expected behavior**
  I expect the .show() and .draw() methods to work for all pipelines, no matter the size.
  This might be a Mermaid problem and not strictly haystacks, but we would need to work to implement a local diagram generator as said in #7896 
  
  **To Reproduce**
  I will not add all the 200 lines of add_component, connect statements, but you can imagine how it goes.
  
  
  **System:**
   - OS: macOS
   - GPU/CPU: M1
   - Haystack version (commit or version number): 2.3.0
