Update ADE for ADO CI/CD

[JFolberth]

This pull request primarily focuses on updates to the Azure deployment environment and related documentation. The major changes include the addition of a new job in the Azure pipeline, updates to the Bicep generator version and template hash in multiple environment deployment files, the addition of a new parameter file for the WebApp environment, and an update to the Terraform documentation.

Azure Pipeline Update:

• .ado/azure-pipelines.yaml: A new job named create_ADE has been added to the Azure pipeline. This job uses the Azure CLI to create a new Azure Deployment Environment (ADE) for a WebApp.

Bicep Generator Updates:

• Environments/FunctionApp/azuredeploy.json, Environments/Sandbox/azuredeploy.json, Environments/WebApp/azuredeploy.json: The Bicep generator version and template hash have been updated in these environment deployment files. [1] [2] [3]

WebApp Environment Update:

• Environments/WebApp/ade.parameters.json: A new parameter file has been added for the WebApp environment with a new parameter named adewebappname.

Documentation Update:

• documentation/terraform-private-preview/README.md: The documentation has been updated with new information about how an Environment Definition needs to be configured when using Terraform. It explains how the Resource Group name is passed to the Terraform file via an internal variable var.resource_group_name.

If need be can include the ADE parameters file in other environment definitions

Hey @JFolberth brought your branch up-to-date due to some merge conflicts and saw that the current generator versions and template hashes are at a higher version than you specified. Is it okay to use the newer version that currently exists on the main branch? Other than that, everything looks good!
