fix: Post-Deployment Script for Managing Bicep Outputs in .env File and Update Conversation flow based on template selection

[Pavan-Microsoft]

Purpose

Post-Deployment Script for Managing Bicep Outputs in .env File and Update Conversation flow based on template selection

User Story 11717: [Bicep] | [CWYD] - Post-Deployment Script for Managing Bicep Outputs in .env File
Bug 11703: [SmokeTesting] - CWYD - Even if we select Conversation flow as "BYOD" while deploying cwyd, once deployed on admin page under configuration it's set to "Cutom" by default.

Does this introduce a breaking change?

• Yes
• [X ] No

How to Test

• Get the code

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

What to Check

Outputs exceeding the 64-item limit are processed and The script formats the consolidated output into .env key-value pairs.
If we select "byod" as conversaion_flow, it should come as "byod" only once deployed, on admin page.
