Title: Replace one letter import in docs
State: closed

This PR updates a code example for consistency across the docs based on [feedback from this comment](https://github.com/huggingface/transformers/pull/20925/files/9fda31634d203a47d3212e4e8d43d3267faf9808#r1058769500):

"In terms of style we usually stay away from one-letter imports like this (even if the community uses them) as they are not always known by beginners and one letter is very undescriptive. Here it wouldn't change anything to use albumentations instead of A."   




Comments:
_The documentation is not available anymore as the PR was closed or merged._

> Thanks for the docs fix for consistency.
> 
> Again for consistency, it would be nice to make the same fix across all the docs, e.g.
> 
> https://github.com/huggingface/datasets/blob/310cdddd1c43f9658de172b85b6509d07d5e31a1/docs/source/image_classification.mdx?plain=1#L41

Excellent point!
