Add AI Configuration Integration (OpenAI, Genini, Genistudio) to backend-starter-cli

[abdullah4tech]

Description:

We need to integrate AI configuration options into the backend-starter-cli package. This should allow users to easily set up and configure AI services such as OpenAI, Geninia, and Genistudio, enabling them to quickly incorporate AI features into their backend projects.

Tasks:

• Add configuration options for OpenAI (API keys, environment variables).
• Add configuration options for Geninia (API keys, environment variables).
• Add configuration options for Genistudio (API keys, environment variables).
• Implement basic setup commands for each service via CLI.
• Update the documentation to reflect new configuration options.

Expected Outcomes:

• Users can seamlessly add AI service configurations to their project.
• Documentation clearly explains how to set up OpenAI, Geninia, and Genistudio.
