fix: Now using ubuntu for better ssl support

[daviroo]

Switch Base Image to Ubuntu 22.04 to Resolve SSL Library Issues

Change Summary

This PR updates the final stage of our Dockerfile from debian:bullseye-slim to ubuntu:22.04 to address runtime errors related to missing SSL libraries.

Rationale

• Primary Reason: Resolves runtime errors caused by missing SSL libraries in the Debian Slim image.
• Ubuntu 22.04 provides better out-of-the-box support for the SSL libraries required by our application.
• This change ensures our service can establish secure connections without additional configuration.

Changes Made

# Final stage
FROM ubuntu:22.04

# Install OpenSSL and ca-certificates
RUN apt-get update && \
    apt-get install -y openssl ca-certificates && \
    rm -rf /var/lib/apt/lists/*

# ... rest of the Dockerfile remains unchanged ...

Impact

• Resolves SSL-related runtime errors, improving the stability and security of our service.
• Slight increase in base image size (Ubuntu is typically larger than Debian Slim).
• Ensures compatibility with OpenSSL and other SSL-related dependencies.

Testing

• [x] Verify that the service builds successfully with the new base image.
• [x] Confirm that SSL-related errors are resolved in the runtime environment.
