fix: Adding a hardcoded createdBy parameter to the RAdeploy.yml file to prevent validation pipeline failures caused by the deployer function in the Bicep file.

[NirajC-Microsoft]

Purpose

This pull request introduces a minor enhancement to the deployment workflow and infrastructure template to improve traceability of resource creation. The main change is the addition of a createdBy parameter that records the pipeline or user responsible for the deployment.

Parameterization and resource tagging:

• .github/workflows/RAdeploy.yml: The Azure deployment command now passes a createdBy="Pipeline" parameter, allowing the infrastructure to record that the deployment was initiated by the pipeline.

• infra/bicep/main.bicep: Added a new createdBy parameter to the Bicep template, which defaults to the deployer's username if not explicitly set. The resource group tags now use this parameter for the CreatedBy tag, enabling better tracking of resource ownership.
