Pull request: [docs] MusicLDM
Fixes #5835 to use a compatible checkpoint

Problem statement:
Using pretrained MusicLDM pipeline
### Describe the bug

Hello, in diffusers docs, MusicLDM is used as follow:
```python
from diffusers import MusicLDMPipeline
import torch
import scipy

repo_id = "cvssp/audioldm-s-full-v2"
pipe = MusicLDMPipeline.from_pretrained(repo_id, torch_dtype=torch.float16)
pipe = pipe.to("cuda")

prompt = "Techno music with a strong, upbeat tempo and high melodic riffs"
audio = pipe(prompt, num_inference_steps=10, audio_length_in_s=5.0).audios[0]

# save the audio sample as a .wav file
scipy.io.wavfile.write("techno.wav", rate=16000, data=audio)
```

But the pretrained path  `cvssp/audioldm-s-full-v2` is seem only compatible with AudioLDM, and can not be used with MusicLDM.
Can you fix the usage of MusicLDM

### Reproduction

```python
from diffusers import MusicLDMPipeline
import torch
import scipy

repo_id = "cvssp/audioldm-s-full-v2"
pipe = MusicLDMPipeline.from_pretrained(repo_id, torch_dtype=torch.float16)
pipe = pipe.to("cuda")

prompt = "Techno music with a strong, upbeat tempo and high melodic riffs"
audio = pipe(prompt, num_inference_steps=10, audio_length_in_s=5.0).audios[0]

# save the audio sample as a .wav file
scipy.io.wavfile.write("techno.wav", rate=16000, data=audio)
```

Hmm why does the full-v2 not work? We should try to always use the official checkpoints if possible

This is the 'official' checkpoint: https://huggingface.co/ucsd-reach/musicldm
```suggestion
        >>> repo_id = "ucsd-reach/musicldm"
```

Thanks, updated with the official checkpoint! :)
