feat: Remove AI search service for PostgreSQL configuration to optimize deployment

[Prasanjeet-Microsoft]

Purpose

• This PR aims to modify the deployment process so that the AI search service is excluded when the database type is set to PostgreSQL. This change optimizes the deployment by removing unnecessary services for PostgreSQL configurations

Does this introduce a breaking change?

• Yes
• No

How to Test

• Get the code

git clone [repo-address]
cd [repo-name]
git checkout [branch-name]
npm install

What to Check

Verify that the following are valid

• Ensure that the AI search service is correctly excluded when the database type is PostgreSQL.
• Verify that the PostgreSQL database configuration works as expected without the AI search service.
• Confirm that other database types, if any, still include the AI search service as required.
• Validate that the deployment process completes without errors.
