Updated documentation for CICD integration

[apybar]

• Updated various documentation for CI/CD pipeline and leveraging the StarterKit

Updates for "Build-PolicyDocumentation":

• Removed requirement to have "enabled" set to true for "documentAllAssignments".
  • Was redundant. Updated logic to see if "documentAllAssignments" is present to know how to proceed rather than the property "enabled" set to true.
• Added optional "PacSelector" parameter for "Out-DocumentationForPolicyAssignments".
  • Used to create markdown and csv files only for the PacSelector provided. Useful when automating file creation to be pushed to Azure DevOps Wiki.
• Added "fileNameStemPrefix" to "documentAllAssignments" section.
  • Used to add a prefix to the 'fileNameStem' set in "documentationSpecifications". Useful when needing to avoid overwriting of files.
• Updated logic for how Wiki Automation works
  • Looks to see if parameter "WikiClonePat" is passed rather than to looking to see if "markdownAdoWikiConfig" is configured in documentation.json
