refactor: Update container image tag to include version detail

[Harsh-Microsoft]

Purpose

This pull request updates the infrastructure templates to improve support for deploying with either new or existing AI Foundry projects, and adds outputs to expose the System Assigned Managed Identity Principal Id. It also updates the way container image tags are specified and referenced. The most important changes are as follows:

AI Foundry Project Integration Improvements:

• Enhanced support for existing AI Foundry projects by extracting subscription ID, resource group, and service name from the existingFoundryProjectResourceId parameter, and referencing the existing project resource directly in the deployment. [1] [2] [3]
• Added aiprojectSystemAssignedMIPrincipalId as an output and parameter in multiple locations, ensuring the System Assigned Managed Identity Principal Id is available for both new and existing AI Foundry projects. [1] [2] [3] [4] [5] [6]

Container Image Tag Parameterization:

• Renamed the container image tag parameter from containerImageTag to imageTag and updated its default value to a new version string; updated all references accordingly in both the Bicep and generated JSON templates. [1] [2] [3]

Role Assignment and Resource Reference Changes:

• Removed explicit role assignment resources for Search Index Data Reader and Search Service Contributor when using new AI projects; instead, for existing projects, the template now references the existing project resource directly, simplifying the deployment logic.

Template Maintenance:

• Updated various template hash values and generator metadata as a result of the above changes and regeneration of the ARM template from Bicep. [1] [2] [3] [4] [5] [6]

These updates make the infrastructure templates more flexible, maintainable, and better aligned with current deployment needs.

Does this introduce a breaking change?
