chore: dev changes to main

[Roopan-Microsoft]

Purpose

• This pull request updates the infrastructure deployment templates to improve how resource group tags are merged and to align with the latest Bicep tooling. The most significant changes enhance tag handling logic for resource groups, update the Bicep compiler version, and correct resource scoping for certain Azure resources.

Tag handling improvements:

• Changed the tag merging logic in both infra/main.bicep and infra/main.json to use the union function instead of shallowMerge, ensuring that resource group tags, user-provided tags, and standard deployment tags are all combined correctly and consistently. This prevents accidental overwrites and ensures all relevant tags are preserved. [1] [2] [3]

Resource scoping fixes:

• Updated the scope property for Cognitive Services resources (locks, diagnostic settings, role assignments) to use the resourceId function instead of string formatting, ensuring more robust and correct resource referencing. [1] [2] [3] [4] [5] [6]

Bicep tooling and metadata updates:

• Upgraded the Bicep compiler version from 0.39.26.7824 to 0.40.2.10011 throughout the generated ARM templates, resulting in updated templateHash values and ensuring compatibility with the latest Bicep features and fixes. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]

Minor corrections and ordering:

• Fixed the ordering of private DNS zone dependencies in the resources list to match expected deployment order.

These changes collectively improve the reliability, maintainability, and correctness of the infrastructure deployment process.
