Issues in the docstrings for Kandinsky pipeline(s)

[freespirit]

Describe the bug

I noticed a few issues with the docstrings in Kandinsky pipelines:

1. Wrong model name in the pipeline_kandinsky.py example:

pipe_prior = KandinskyPriorPipeline.from_pretrained("kandinsky-community/Kandinsky-prior")

should be

pipe_prior = KandinskyPriorPipeline.from_pretrained("kandinsky-community/kandinsky-2-1-prior")

2. The KandinskyPriorPipelineOutput's members were renamed in 32ea214 but the relevant docstrings throughout the Kandinsky pipelines were not. For example, the src/diffusers/pipelines/kandinsky/pipeline_kandinsky.py has this docstring:

pipe_prior = ...
out = pipe_prior(prompt)
image_emb = out.images
zero_image_emb = out.zero_embeds

In addition to using the correct member names, I would suggest renaming the variables:

pipe_prior = ...
out = pipe_prior(prompt)
image_emb = out.image_embeds
negative_image_embeds = out.negative_image_embeds

Reproduction

from diffusers import KandinskyPipeline, KandinskyPriorPipeline
import torch

pipe_prior = KandinskyPriorPipeline.from_pretrained("kandinsky-community/Kandinsky-prior") # wrong model id
pipe_prior.to("cuda")

prompt = "red cat, 4k photo"
out = pipe_prior(prompt)
image_emb = out.images # wrong name
zero_image_emb = out.zero_embeds # wrong name
