Reduce the number of installed packages to decrease Docker image size

[ulan-yisaev]

Hi, I'm currently using ragchecker with only the Azure AI connectors and noticed that a significant number of dependencies are installed even though they are not required for my use case. This results in a large Docker image size, which I'd like to minimize.

Would it be possible to reduce the number of installed packages or offer a more modular installation method (e.g., extras or specific connectors)? This would help users tailor the installation based on the features they need and reduce image sizes.

Thanks in advance!
