Refine axolotl 0.3.0 documents and links (#10764)

* Refine axolotl 0.3 based on comments
* Rename requirements to requirement-xpu
* Add comments for paged_adamw_32bit
* change lora_r from 8 to 16

 ```bash
 source /opt/intel/oneapi/setvars.sh
 ```
 
-Config `accelerate`
+Configures `accelerate` in command line interactively. 
 
 ```bash
 accelerate config
 ```
 
-Ensure `use_cpu` is disable in config (`~/.cache/huggingface/accelerate/default_config.yaml`).
+Please answer `NO` in option `Do you want to run your training on CPU only (even if a GPU / Apple Silicon device is available)? [yes/NO]:`.
 
-### 3. Finetune
+After finish accelerate config, check if `use_cpu` is disable (i.e., ` use_cpu: false`) in accelerate config file (`~/.cache/huggingface/accelerate/default_config.yaml`).
