Adding Support for Deletion of custom ARM and Bicep template resource

[Jefajers]

Overview/Summary

This PR expands deletion support from a handfull of AzOps generated templates to include both AzOps generated resource group templates/folders and custom ARM and Bicep templates while bumping module dependencies for Az.Accounts 2.16.0 and Az.Resources 6.16.0.

Closes #785 and fixes #849, with improved deleted content serialization logic.

Deletion of custom ARM and Bicep template resource is disabled by default. To enable it, set Core.CustomTemplateResourceDeletion to true. Be aware, once this feature is turned on, AzOps will attempt resource deletion for each identifed resoruce id contained in the template and parameter file, read more in the wiki.
