Update Dockerfile for Compatibility and Dependency Fixes

[siddicky]

Summary

The current Dockerfile needs updates due to outdated Debian sources and dependency conflicts that prevent the image from building successfully.

Details

The following changes are proposed to address the issues:

• Debian Sources Update:

Change Debian sources to point to the Debian Archive since Debian Stretch is no longer actively maintained.

Remove stretch-updates from the sources list as it’s no longer available.

• Dependency Fixes:

Upgrade pip to the latest version to ensure compatibility with package installations.

Install cryptography==3.3.2 to avoid the need for Rust during installation, which newer versions require.

Install python-miio==0.5.4, a version compatible with the older dependencies and Python 3.
