Implement Dynamic baseUrl for Flexible Deployments

This PR introduces a dynamic baseUrl configuration for Docusaurus, enabling flexible deployments and improving our ability to verify changes in preview environments.

Problem

Previously, we were unable to effectively test PR changes in preview deployments. Setting the baseUrl to '/docs/' caused Docusaurus assets and CSS to break in these preview environments.

Solution

Implemented a dynamic baseUrl configuration that adapts to different deployment environments:

• For production: baseUrl is set to '/docs/'
• For preview deployments: baseUrl defaults to '/'

This approach allows us to:

1. Maintain the correct configuration for our production site at abc.com/docs
2. Properly render and test changes in preview deployments

Environment Variable Setup

For production deployments only, add the following environment variable:

BASE_URL=/docs/

Important: Do not add this environment variable for preview deployments. The absence of this variable will default baseUrl to '/', ensuring correct functionality in preview environments.

Please review and test this change thoroughly in both preview and production environments.
