fix: merging dev changes to main

[Roopan-Microsoft]

Purpose

• This pull request introduces significant enhancements to the Azure deployment configuration and infrastructure for the "modernize-your-code-solution-accelerator" project. The main changes include the addition of a custom deployment template, improvements to redundancy and monitoring for Log Analytics workspaces, updates to infrastructure modules for better reliability and security, and expanded documentation to guide users through advanced deployment and resource deletion scenarios.

Infrastructure and Redundancy Improvements:

• Added a new deployment configuration file azure_custom.yaml to support custom deployments, including explicit service definitions and infrastructure provider selection.
• Enhanced Log Analytics workspace configuration in infra/main.bicep to support redundancy, including replica region mapping, daily quota, and conditional settings for private networking and monitoring. [1] [2]
• Updated several Bicep modules to newer versions for managed identity, Log Analytics, Application Insights, DNS zones, Bastion Host, and container apps, improving reliability and security. [1] [2] [3] [4] [5] [6] [7]

Monitoring and Virtual Machine Enhancements:

• Overhauled the Jumpbox VM setup to use a new maintenance configuration, proximity placement group, and detailed monitoring/data collection rules, including anti-malware and network watcher extensions. These changes align with WAF recommendations and improve observability and patching. [1] [2]

Documentation Updates:

• Added a new guide docs/LogAnalyticsReplicationDisable.md to help users disable Log Analytics replication before resource deletion, preventing deployment errors and providing CLI instructions.
• Updated docs/DeploymentGuide.md with instructions for deploying local changes using custom template files and handling resource deletion when redundancy is enabled.

General Configuration Updates:

• Updated default image version for backend containers and other minor parameter defaults for improved compatibility and future-proofing.

These changes collectively improve deployment flexibility, reliability, monitoring, and user guidance for managing Azure resources in this solution accelerator.
