Update environment variables for the latest Librechat version

[derbuihan]

Summary

To conform to the updated setup instructions for Librechat's Azure OpenAI setup process, I've updated the Terraform configuration in this repository in order to ensure its compatibility with the latest version of Librechat.

Changes Made

1. db.tf, openai.tf, outputs.tf and variables.tf:

   • Executed terraform fmt.
   • The preview models have been commented out.

2. webapps.tf:

   • The environment variables have been updated to reflect the latest version of Librechat based on the .env.example. Please refer to this guide for more information.

Testing and Verification

• For testing purposes, I executed the terraform apply command with the updated Terraform configuration. The results indicate prospective resources have been provisioned correctly and accordingly.
• Furthermore, I set up an actual Azure environment using these configurations and was able to confirm that Librechat operates smoothly.

Reference

I utilized the instructions specified in the code section found here for reference.
