Modify pipeline_tutorial.mdx (#22726)

generator(model="openai/whisper-large") always returns error. As the error says the generator expects an input, just like the .flac file above. Even the generator object has no parameters called model. While there are parameters which can be passed to generator like 'batch_size' but to pass a model i believe the the parameter has to be passed while instantiating the pipeline and not as a parameter to the instance.

I believe the correct term should be:

generator = pipeline(model="openai/whisper-large", device=0)

 In general you can specify parameters anywhere you want:
 
 ```py
-generator(model="openai/whisper-large", my_parameter=1)
-out = generate(...)  # This will use `my_parameter=1`.
-out = generate(..., my_parameter=2)  # This will override and use `my_parameter=2`.
-out = generate(...)  # This will go back to using `my_parameter=1`.

 If the model is too large for a single GPU, you can set `device_map="auto"` to allow 🤗 [Accelerate](https://huggingface.co/docs/accelerate) to automatically determine how to load and store the model weights.
 
 ```py
 #!pip install accelerate
-generator(model="openai/whisper-large", device_map="auto")
+generator = pipeline(model="openai/whisper-large", device_map="auto")
 ```
 
 Note that if  `device_map="auto"` is passed, there is no need to add the argument `device=device` when instantiating your `pipeline` as you may encounter some unexpected behavior!
