Cannot use monai-deploy package by following offical tutorial

Describe the bug
I followed this tutorial and failed.

I though is the conda environment problem until I found this tutorial without using conda.

so I simplify the steps as follow:

To Reproduce
Steps to reproduce the behavior:

1. run command:

pip install fsspec
pip install monai-deploy-app-sdk

2. Install cuda-toolkit.

3. run command:

export PATH=/usr/local/cuda-12.5/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-12.5/lib64:$LD_LIBRARY_PATH
sudo apt install docker-buildx
git clone --branch main --depth 1 https://github.com/Project-MONAI/monai-deploy-app-sdk.git
cd monai-deploy-app-sdk
pip install scikit-image setuptools Pillow matplotlib
chmod +777 /tmp/requirements.txt
monai-deploy package examples/apps/simple_imaging_app -c examples/apps/simple_imaging_app/app.yaml -t simple_app:latest --platform x64-workstation -l DEBUG

Expected behavior
Stop here:

Environment
AWS EC2 NVIDIA GPU Optimized AMI. g5.xlarge instance

Start with the linked simple app tutorial, the packaging command, and the generated Dockerfile at line 72, where installation of /tmp/requirements.txt fails with permission denied. Reproduce the build in the stated AWS EC2 NVIDIA GPU environment and compare the requirements-file permissions during image construction. Done means the official tutorial's packaging command completes successfully without the reported Docker build error.
