Prepare RestSetAcls for PowerShellGallery publish

[MaximeKjaer]

Sets up the RestSetAcls module for publishing on PSGallery. Most of the work here is to ensure we follow the publishing guidelines and best practices, including:

• Added psd1 declaring dependencies (see Manage Dependencies best practice).
• Dev tools to try the publishing step on a local repository (see local repo best practices)
• Added GitHub Actions that run on every commit push and on every PR (only for changes to RestSetAcls), to check:
  • PSScriptAnalyzer warnings (see PSScriptAnalyzer best practice)
  • Pester tests (see testing best practice)
  • Test-ModuleManifest to ensure the psd1 is correct
