Queuing related guides contain outdated information about concurrency_count

[the-eddie]

Describe the bug

These guides related to queuing still refer to concurrency_count:

• Queuing
• Setting Up a Demo for Maximum Performance

However, as confirmed in #9463:

The concurrency_count parameter has been removed from .queue(). In Gradio 4, this parameter was already deprecated and had no effect. In Gradio 5, this parameter has been removed altogether.

Running the code from Queuing guide results in the error below:

Exception has occurred: TypeError
EventListener._setup.<locals>.event_trigger() got an unexpected keyword argument 'concurrency_count'
  File "./test_gradio.py", line 23, in <module>
    greet_btn.click(fn=greet, inputs=[tag, output], outputs=[
TypeError: EventListener._setup.<locals>.event_trigger() got an unexpected keyword argument 'concurrency_count'

I've figured out what the problem is and reproduced, but I'd like to confirm that the work needed is to remove that part of the documentation about concurrency_count, right? There is no need for additional deletion instructions. I'll swap out the code use case for a working use case. @freddyaboulton

I've also noticed that concurrency_limit parameter isn't mentioned in the documentation, what do you think about adding it to the documentation? @freddyaboulton
