Update Dockerfile to include Python for dependency installation

[pushpitkamboj]

followed the steps in doc.md, but encountered an error — the Docker container also requires Python to install some dependencies. It would be helpful to add one more setup step: install Python in the Docker container.

If you’re submitting this as a suggestion or PR comment, you could frame it like:

⚠️ While following the setup steps in doc.md, I ran into an issue — some dependencies require Python, which isn’t available in the Docker container by default.
🔧 Suggest adding a step to install Python in the Dockerfile to prevent this error.

Hey! 👋 @pushpitkamboj
I was setting things up by following the steps in doc.md, and I hit a small snag — some dependencies need Python, but it looks like Python isn’t available in the Docker container by default.

Would recommend adding a quick step in the Dockerfile to install Python. Something like:

RUN apt-get update && apt-get install -y python3 python3-pip
