fix: merging dev changes to main branch

[Roopan-Microsoft]

Purpose

This pull request updates the Teams extension to support single-tenant authentication for the bot and ensures proper Azure resource provisioning. The changes include switching the bot registration and configuration to single-tenant mode, passing the tenant ID throughout the deployment pipeline, and adding automation to enable a service principal for the bot application.

Authentication and Bot Registration

• Changed bot registration from multi-tenant to single-tenant by updating MicrosoftAppType and adding MicrosoftAppTenantId in index.ts and ARM/Bicep templates. This enforces authentication to a specific tenant. [1] [2]
• Added tenantId to the runtime configuration (config.ts) and ensured it is provided via environment variables and deployment templates. [1] [2] [3]

Infrastructure and Deployment

• Updated Bicep templates to accept and propagate the tenant ID parameter for bot registration, and increased the maximum length for resource names to avoid deployment issues. [1] [2] [3]

Automation and Developer Experience

• Added a script (enable-service-principal.js) and corresponding npm command to automatically create a service principal for the bot application using Azure CLI, improving deployment reliability. [1] [2] [3]

Build Configuration

• Updated TypeScript configuration to use Node 16 module and resolution settings for compatibility with newer Node.js features.
